Color theory is both the science and art of using color. It explains how humans perceive color; and the visual effects of how colors mix, match or contrast with each other. Color theory also involves the messages colors communicate; and the methods used to replicate color Color is perception. Our eyes see something (the sky, for example), and data sent from our eyes to our brains tells us it’s a certain color (blue). Objects reflect light in different combinations of wavelengths. Our brains pick up on those wavelength combinations and translate them into the phenomenon we call color. Color theory is the basis for the primary rules and guidelines that surround color and its use in creating aesthetically pleasing visuals. By understanding color theory basics, you can begin to parse the logical structure of color for yourself to create and use color palettes more strategically. The result means evoking a particular emotion, vibe, or aesthetic. The right contrast is vital to catching users’ attention in the first place. The vibrancy you choose for your design is likewise crucial to provoking desired emotional responses from users. How they react to color choices depends on factors such as gender, experience, age and culture. In all cases, you should design for accessibility – e.g., regarding red-green color blindness. Through UX research, you can fine-tune color choices to resonate best with specific users. Your users will encounter your design with their own expectations of what a design in a certain industry should look like. That’s why you must also design to meet your market’s expectations geographically. For example, blue—an industry standard for banking in the West—also has positive associations in other cultures. However, some colors can evoke contradictory feelings from certain nationalities (e.g., red: good fortune in China, mourning in South Africa, danger/sexiness in the USA). Overall, you should use usability testing to confirm your color choices

2. WHAT IS COLOR THEORY?
Color theory is the
art of combining
colors based on the
color wheel, an
organized
illustration of the
primary, secondary,
and tertiary colors.

3. WHAT IS COLOR WHEEL?
The color wheel consists of three primary colors (red, yellow,
blue), three secondary colors (colors created when primary
colors are mixed: green, orange, purple) and six tertiary
colors (colors made from primary and secondary colors, such as
blue-green or red-violet).

4. WHAT ARE WARM COLORS AND COOL COLORS ?
Warm colors are generally
associated with energy,
brightness, and action. Warm
colors are those in the red,
orange, and yellow families
Cool colors are often identified with
calm, peace, and serenity. Cool
colors are those in the green, blue,
and purple families

5. WHAT ARE HUES, TONES, TINTS AND SHADES ?
Hue: A pure
pigment.
Tone: A pure
pigment with
just grey
added.
Tint: A pure
pigment
with just
white
added.
Shade: A pure
pigment with
just black
added.

6. TYPES OF COLOR SCHEMES
1. Complementary colors
Complementary colors are
opposites on the color wheel—
red and green
2.Analogous colors
Analogous colors sit next to
one another on the color
wheel—red, orange and yellow

7. 3.Triadic colors
Triadic colors are evenly
spaced around the color
wheel and tend to be very
bright and dynamic.
4.Monochromatic
Monochromatic color schemes
use a single color with varying
shades and tints to produce a
consistent look and feel.

8. 5.Split Complementary
A split complementary scheme
includes one dominant color
and the two colors directly
adjacent to the dominant
color's complement
6. Tetradic
The square color scheme uses
four colors equidistant from
each other on the color wheel
to create a square or diamond
shape
