The document discusses color theory and the principles of color mixing and harmony. It explains that color is the visual property corresponding to categories like red and blue. Primary colors are red, yellow and blue, and can be mixed to produce secondary colors like green, purple and orange. Tertiary colors are mixes of primary and secondary colors. The color wheel is used to select harmonious color combinations like complementary, analogous, warm, and cool colors. Proper use of color theory principles allows for effective color scheme design.

2. Color / Colour is the visual perceptual property corresponding in humans
to the categories called red, blue, yellow, green and others.
Color derives from the spectrum of light (distribution of light power versus
wavelength) interacting in the eye with the spectral sensitivities of the light
receptors.

3. Color categories and physical specifications of color are also associated with objects, materials, light sources, etc.,
based on their physical properties such as light absorption, reflection, or emission spectra.
Because perception of color stems from the
varying spectral sensitivity of different types of
cone cells in the retina to different parts of the
spectrum, colors may be defined and quantified
by the degree to which they stimulate these cells.

4. Primary Colors - These are colors that cannot be created through the mixing
of other colors. They are colors in their own right. The three primary colors can
be seen below RED - YELLOW - BLUE.

5. Primary colors can be mixed together to produce SECONDARY
COLOURS. Yellow mixes with blue in equal quantity will gives you
green

9. Tertiary colors are combinations of primary and secondary
colors.
There are six tertiary colors; red-orange, yellow-orange, yellow-
green, blue-green, blue-violet, and red-violet.
An easy way to remember these names is to place the primary
name before the other color.
So the tertiary color produced when mixing the primary color
blue with the secondary color green, is called 'blue-green'.

10. The color wheel or color circle is the basic tool for combining
colors. The first circular color diagram was designed by Sir Isaac
Newton in 1666. The color wheel is designed so that
virtually any colors you pick from it will
look good together.
Over the years, many variations of the
basic design have been made, but
the most common version is a wheel of
12 colors based on the RYB (or artistic)
color model.

11. Tints are light values that are made by mixing a color with white. For example, pink
is a tint of red, and light blue is a tint of blue.
Shades are dark values that are made by mixing a color with black. Maroon is a
shade of red, and navy is a shade of blue.

12. Tones nothing but the true colors and if gray is added, the result is a
different tone.
The given example clearly shows the tonal variations and colors will lose
its nature that’s why it looks peculiar.

13. Colors opposite to each other in color wheel is said to be
complementary colors. Because they are opposites, they tend to look
especially lively when used together. When you put complementary
colors together, each color looks more noticeable.

14. Analogous colors sit next to each other on the color wheel. They tend
to look pleasant together because they are closely related.

15. Neutral colors don't usually show up on the color wheel. Neutral colors include
black, white, gray, and sometimes brown and beige. They are sometimes
called “earth tones.”

16. Warm colors are made with red, orange, yellow, or some
combination of these. Warm colors tend to make you think of sunlight
and warmth.
Ar.A.Purushothaman Arumugam M.Arch., CA, AIIA, Principal Architect - D2 Studios.

17. Cool colors are made with blue, green, purple, or some combination
of these. Cool colors might make you think of cool and peaceful
things, like winter skies and still ponds.

18. Triadic
A triadic color scheme uses colors that are evenly spaced around the color wheel.
Triadic color schemes tend to be quite vibrant, even if you use pale or unsaturated
versions of your hues.
To use a triadic harmony successfully, the colors should be carefully balanced - let one
color dominate and use the two others for accent.

19. Split
The split-complementary color scheme is a variation of the complementary color scheme.
In addition to the base color, it uses the two colors adjacent to its complement.
This color scheme has the same strong visual contrast as the complementary color scheme, but has
less tension.
The split-complimentary color scheme is often a good choice for beginners, because it is difficult to
mess up. Ar.A.Purushothaman Arumugam M.Arch., CA, AIIA, Principal Architect - D2 Studios.

20. Colors red yellow and green create a harmonious design, regardless of
whether this combination fits into a technical formula for color harmony.

21. How color behaves in relation to other colors and
shapes is a complex area of color theory. Compare
the contrast effects of different color backgrounds for
the same red square.
Observing the effects colors have on each other is the
starting point for understanding the relativity of color. The
relationship of values, saturations and the warmth or
coolness of respective hues can cause noticeable
differences in our perception of color.
