2. Literature Review on Bridging the Colour Gap: Designing
Inclusive Experiences for Color Blindness
Abstract
Research in the field of inclusive design for colour blindness has made significant
strides in recent years. Several studies have focused on understanding the unique
challenges faced by individuals with colour vision deficiency and have proposed
various strategies to bridge the colour gap in design. One approach involves the use
of alternative colour combinations, patterns, and textures to convey information
effectively to both colour-sighted and colour-blind users.
Advancements in technology have led to the development of digital tools and
software that enable designers to simulate how their designs appear to individuals
with different types of colour vision deficiency. These tools can help designers
identify potential issues and make informed decisions to create more inclusive
experiences.
Furthermore, there has been an increasing emphasis on raising awareness about
colour blindness and promoting the importance of considering diverse user needs in
design practices. This shift towards inclusivity has led to the integration of universal
design principles, ensuring that products and services are accessible to a wider
range of users, including those with colour vision deficiency.
In addition to academic research, industry reports and authoritative websites provide
valuable insights into best practices and emerging trends in designing for colour
blindness. By drawing from a diverse range of sources, designers and researchers
can gain a comprehensive understanding of the challenges and opportunities in this
area.
As the field continues to evolve, it is essential for designers and researchers to stay
updated with the latest developments and best practices in inclusive design for
colour blindness. By doing so, they can contribute to creating a more inclusive and
accessible environment for all individuals, regardless of their colour vision abilities.
In conclusion, designing inclusive experiences for colour blindness is a crucial
aspect of creating accessible and user-friendly designs. It requires designers to
consider the specific needs and challenges of individuals with colour vision
deficiency and implement best practices in their design process. These best
practices include providing sufficient contrast between colours and textures, using
alternative means of conveying information (such as patterns or textures), and
utilising digital tools to simulate how designs appear to colour-blind individuals.
Furthermore, promoting awareness about colour blindness and integrating universal
design principles are essential for creating inclusive experiences.

3. In addition, designers should stay updated on the latest research and tools available
for simulating and testing designs for colour blindness. By incorporating these
practices and staying informed, designers can play a significant role in bridging the
colour gap and creating inclusive experiences for individuals with colour blindness.
Overview of Color Blindness
Colour blindness, or colour vision deficiency (CVD), is a condition characterised by
the inability to perceive certain colours or differences in colours. It affects a
significant portion of the population, with estimates suggesting that around 1 in 12

4. men (8%) and 1 in 200 women are colorblind (approximately 4.5% of the world
population),worldwide have some form of colour vision deficiency. This condition
arises due to abnormalities in the photopigments within the cones of the retina,
leading to difficulties in distinguishing between certain colours or shades.
Colour blindness can have a variety of effects on day-to-day living, from making it
difficult to choose clothes to having trouble reading maps or interpreting traffic
signals. These difficulties highlight the value of inclusive design, which attempts to
produce goods, settings, and encounters that take into account the requirements of
every person, including those who have colour vision impairments.
Importance of Inclusive Design
Meeting the needs of people who are colour blind requires the use of inclusive
design. Through the implementation of inclusive design principles, designers can
guarantee that their products are usable by a wider spectrum of users, encouraging
equitable engagement and improving user experience for all. This strategy promotes
diversity and inclusivity in society at large in addition to helping those who suffer from
colour vision deficiencies.Purpose and Scope of the Research
This study aims to investigate the relationship between colour blindness and
inclusive design, looking at opportunities, problems, and current approaches to
creating inclusive experiences for people with colour vision impairments. The
purpose of the study is to clarify the significance of inclusive design in meeting the

users, ultimately bridging the colour gap and promoting digital accessibility
for all.

6. Types of colour blinds with limitation
The types of colour blindness include red-green colour blindness, blue-yellow colour
blindness, and total colour blindness (monochromacy). Red-green colour blindness
is the most common type, affecting the perception of red and green colours due to
issues with L cones (red-sensing cones) and M cones (green-sensing cones).
Blue-yellow colour blindness, known as tritan defects, is rarer and results in difficulty
distinguishing blue and yellow colours. Monochromacy, or achromatopsia, is the
most severe form where individuals see everything in shades of grey due to missing
or non-functioning cones. These conditions can be inherited or acquired, impacting
colour perception to varying degrees.
Limitations:
Colour blindness, also known as colour vision deficiency (CVD), encompasses
several types, each characterised by specific impairments in perceiving colours
accurately. The main types of colour blindness include:
1. Red-Green Color Blindness: This is the most common type of colour blindness,
affecting the perception of red and green colours. It includes subtypes such as:
- Protanomaly: Individuals with this type have a reduced sensitivity to red light.
- Deuteranomaly This subtype involves a reduced sensitivity to green light.
2. Blue-Yellow Color Blindness (Tritan defects): This type affects the ability to
differentiate between blue and yellow colours. It is rarer than red-green
colorblindness.
3. Total Colour Blindness (Monochromacy): Also known as achromatopsia, this is
the most severe form of colour blindness. Individuals with monochromacy see the

7. world in shades of grey due to the absence or non-functioning of cones, the
photoreceptor cells responsible for colour vision. Monochromacy can further be
categorised into:
- Rod Monochromacy: Absence of all cone cell types, resulting in black, white, and
shades of grey vision.
- Cone Monochromacy Absence of one or two cone types, leading to colour vision
with only one or two primary colours.
Each type of colour blindness presents unique challenges in perceiving and
distinguishing colours accurately, impacting various aspects of daily life and
interactions with digital interfaces.
Prevalence and Impact of Color Vision Deficiency
Colour vision deficiency affects a significant portion of the population worldwide.
Studies suggest that approximately 1 in 12 men (8%) and 1 in 200 women are
colorblind (approximately 4.5% of the world population),and have some form of
colour vision deficiency. While the condition is more prevalent in males due to its
X-linked inheritance pattern, it can occur in individuals of any gender.
The impact of colour vision deficiency extends beyond difficulties in discerning
colours accurately. Affected individuals may encounter challenges in various aspects
of daily life, including:
Occupational limitations:Accurate colour perception may be necessary for a number
of occupations, including graphic design, electrical wiring, and transportation.
Colorblind people may encounter obstacles or limitations when attempting to pursue
these professions.
Educational challenges:Educational resources and materials that are colour-coded
can present difficulties for students who have colour vision deficiencies.
Colour-coded data in maps, graphs, and charts can be especially difficult to
understand.
Social and emotional effects:When people with colour vision deficiencies are unable
to participate in certain activities or are in social situations where conversations
about colour perception are prevalent, they may feel frustrated, alone, and
inadequate.

8. Historical Context and Societal Implications
Over time, scientists, researchers, and advocates have made significant
contributions to the evolving understanding of colour blindness. The first account of
the condition dates back to the 18th century and was written by the scientist John
Dalton, who was also colorblind. Since then, developments in the fields of genetics
and ophthalmology have helped us better understand the mechanisms underlying
colour vision deficiency.Colour vision impairments have an impact on many different
sectors and industries in society. For example, the prevalence of colorblind people in
design and marketing requires the use of inclusive design principles to guarantee
that environments, services, and goods are usable by all users. Furthermore, laws
and accessibility guidelines have been proposed in an effort to support diversity and
meet the needs of those who are colorblind.It is crucial to comprehend the different
kinds, prevalence, and effects of colour vision deficiency in order to promote
accessibility and inclusivity in a variety of social contexts. Through the recognition of
the difficulties encountered by colorblind people and the application of inclusive
design principles, we can establish more fair and accommodating surroundings for
all.

9. Colours they can see
People with colorblindness, also known as colour vision deficiency, have difficulty
perceiving and differentiating certain colours due to abnormalities in the
colour-sensing pigments of the cones in the retina. The types of colours individuals
with colour blindness can see depend on the specific type of colour vision deficiency
they have:
1. Red-Green Color Blindness:
● Protan-type Colour Blindness: Individuals with protan-type colour
blindness have a deficiency in the red-sensing cones (L-cones). They
tend to see greens, yellows, oranges, reds, and browns as more similar
shades of colour than normal. Purple colours may look more like blue,
and pink colours can appear grey or dull.
● Deutan-type Colour Blindness: Deutan colour blindness affects the
green-sensing cones (M-cones). People with deutan-type colour
blindness may confuse colours like green and yellow, or blue and
purple. Green traffic signals may appear very pale green or white. They
may also have difficulty distinguishing between pink and grey or white.
2. Blue-Yellow Color Blindness (Tritanomaly and Tritanopia):
● Tritanomaly: In tritanomaly, the short-wavelength cones (S-cones) are
present but dysfunctional. This can cause blue and green to look alike,
and red and yellow to appear similar.

10. ● Tritanopia: Tritanopia occurs when the S-cones are missing, leading to
colours looking dampened and difficulty in differentiating between
colours.
3. Complete Colour Blindness (Monochromacy):
● Individuals with complete colour blindness see the world in shades of
grey, black, and white. This condition, also known as achromatopsia, is
extremely rare and results in a lack of colour perception.
While individuals with colour blindness may have limitations in perceiving certain
colours accurately, they can still see a range of colours, albeit with variations and
challenges. The specific colours they can see depend on the type of colour vision
deficiency they have, with some colours appearing similar or different from how
individuals with normal colour vision perceive them.
WCAG: A Deeper Dive (In Depth):
● WCAG (Web Content Accessibility Guidelines) is a crucial resource for
building accessible websites. It outlines specific criteria for things like colour
contrast, keyboard navigation, and clear language.
● While WCAG serves as our guiding principle, we recognize it's not the only
factor.
● We go beyond the baseline by conducting usability tests with real people to
identify any areas where users might struggle.
● Additionally, we stay up-to-date on accessibility best practices by
incorporating insights from fellow researchers.
● It's important to note that WCAG doesn't mandate strict accessibility
requirements for purely decorative images.
● However, our commitment to inclusivity extends beyond the minimum
standards. We strive to make all visuals, even decorative images, easier to see
for everyone.
● Ultimately, our goal is to empower you, the user. We want to provide a wide
range of options so you can personalise your experience and choose what
works best for you in terms of comfort and ease of use. By doing so, we aim
to create a truly inclusive learning environment that caters to diverse user
preferences.

11. Challenges in Designing for Colour Blindness
Designing for colour blindness presents several challenges that designers and
developers must address to ensure inclusivity and accessibility for colorblind users.
This section explores common design issues for colorblind individuals, examples of
inaccessible designs, and the impact of colour blindness on various domains,
including web design, graphic design, and gaming.
Common Design Issues for Colorblind Users
Over-reliance on Colour: Colour is often used in designs to communicate
information, as in the case of data representation through colour-coded graphs or
charts. Such images may be difficult for colorblind people to comprehend correctly,
which can result in misconceptions or misinterpretations.
Poor Colour Contrast: Colorblind users may find it challenging to navigate designs
with low colour contrast. For example, people with colour vision deficiencies may
find it difficult to read text superimposed on images with similar colour tones.
Colour-Coded Instructions: Colorblind users may experience difficulties when
presented with cues or instructions that lack alternative identifiers. For example,
people with specific types of colour vision deficiencies might not be able to
distinguish between call-to-action buttons and colour-coded navigation buttons.
Inaccessible Maps and Charts: Users who are colorblind may not be able to access
maps and charts that use colour alone to distinguish between elements, such as
territories or data points. Colorblind people could find it difficult to correctly interpret
the information without additional visual cues or labels.
Examples of Inaccessible Designs
Website Navigation: Users who are colorblind may not be able to access websites
that rely solely on colour to indicate whether a link is active or inactive. Colorblind
people might find it difficult to distinguish between clickable and non-clickable
elements without alternative cues, like bold text or underlining.
Data Visualisation: People who are colorblind may find it difficult to understand
colour-coded graphs or charts in presentations or reports. For instance, people with

12. colour vision deficiencies may find it challenging to correctly interpret a pie chart that
uses different colours to represent different segments.
Gaming Interfaces: Colorblind players may not be able to interact with video games
that use colour to display vital information, such as health bars or enemy indicators.
In the absence of alternate visual cues or customisation options, colorblind players
might find it difficult to participate completely in the game.Impact on Various
Domains
Web design: Users who are colorblind may have trouble navigating websites with
colour-coded instructions, inaccessible navigation menus, or poor colour contrast.
These issues can be addressed with the aid of inclusive web design techniques,
such as offering customisable colour options and employing alternative text for
images.
Graphic Design: Colorblind people may have trouble understanding infographics,
charts, or other colour-coded graphics. By using alternate visual cues, like patterns or
symbols, and carrying out accessibility testing with colorblind users, graphic
designers can lessen these difficulties.
Gaming: Colorblind players might have trouble telling apart different elements of the
game or deciphering colour-coded instructions. By including customisable colour
settings, alternate visual cues, and playtesting with colorblind people, game
developers can increase accessibility for colorblind players.
Principles of Inclusive Design
The goal of inclusive design is to provide experiences, environments, and goods that
are usable and accessible to as many people as possible, irrespective of their

High Contrast: To guarantee colorblind users can read and see your content, use
colour combinations with high contrast. To improve the legibility and clarity of visual
elements, choose colours that have different brightness levels, like black and white
or dark and light hues.
Colour Consistency: To ensure coherence and prevent confusion, use the same
colours throughout the design. Use consistent colour associations for similar
elements or actions and establish a colour palette consisting of a small number of
distinct hues.
Accessible Colour Choices: Select hues that people with colour vision deficiencies
can easily distinguish. Steer clear of colour combinations like red-green or
blue-yellow that could be difficult for people who are colorblind to distinguish.
Alternative Design Approaches (e.g., Texture, Pattern, Shape)
Texture and Pattern: Incorporate texture or pattern into designs to provide additional
visual cues and differentiate between elements. Texture-rich designs can enhance
usability for colorblind individuals by offering alternative methods for conveying
information and guiding interaction.
Shape Recognition: Utilise distinct shapes or symbols to represent different
elements or actions within the design. Shapes provide an alternative means of
differentiation that is independent of colour, enabling colorblind users to interpret
content accurately.
Iconography and Symbolism: Integrate meaningful icons or symbols alongside
colour-coded elements to convey information effectively. Icons serve as alternative
visual cues that complement colour differentiation and enhance usability for all
users, regardless of colour vision abilities.

16. Tools and Resources for Testing Designs with Colorblind Users
Colorblindness Simulators: These tools allow you to see how designs would appear

accessibility requirements and ensure that digital products and services remain
accessible to all users.
In conclusion, future directions and opportunities in inclusive design are
characterised by the integration of emerging technologies, interdisciplinary research
efforts, and a commitment to continuous improvement and adaptation. By
embracing innovation, collaboration, and user-centric design principles, stakeholders
can create more accessible, usable, and equitable digital experiences that empower
individuals of all abilities to participate fully in the digital world.
Accessibility and colour designing for colour blind user

23. Making a website colour blind-friendly does not mean that you should avoid using
the colours associated with these forms of colour blindness. There are many tools
that can help you with accessibility during the design and development stage.
Stark
If you use Sketch then this is a great tool for seeing the effects to your designs on
the fly.
Color Oracle
This applies a full-screen colour filter independent of any applications, which means
that you can design in real-time and see how it is affected.
Color Scheme Designer
This is good for checking complimentary colours and viewing how they will be seen
by colour blind people. Simply select your colour ranges and use the Colorblind
drop-down.
Image Color Blind Simulator
This is great for emulating how a design will be seen by people with various forms of
colour blindness. This is probably most useful for checking logos or call-to-action
type designs.
Colorblind Web Page Filter
This is great for comparing a built page URL against various forms of colour
blindness. It’s a bit slow on the initial fetch and filter, but after that, it’s reasonably
fast.
Color Contrast Checker
If you use a compiler during development, this can be installed via npm and will run
every time you compile. A warning will appear in your console if anything does not
meet the standards. This can be handy if you set up your styles first and missed
something during design, the usual culprit being the hover states.
Conclusion
So as you can see, there are many tools out there to help with your website
accessibility and colour, with a lot of them able to be used unobtrusively as you work.

24. If you work within a team, then I would advise that the colours have already been
through the test process before it gets to development as it could cause some
headaches later
