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.

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.


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.


Primary colors can be mixed together to produce SECONDARY

COLOURS. Yellow mixes with blue in equal quantity will gives you

green



COLOURS. Blue combines with red in equal proportion will gives you

purple…,



COLOURS. Red combines with yellow in equal proportion will gives

you orange…,



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'.Ar.A.Purushothaman Arumugam M.Arch., CA, AIIA, Principal Architect - D2 Studios.

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.Ar.A.Purushothaman Arumugam M.Arch., CA, AIIA, Principal Architect - D2 Studios.

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.


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.


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.


Analogous colors sit next to each other on the color wheel. They tend

to look pleasant together because they are closely related.


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.”


Warm colors are made with red, orange, yellow, or some

combination of these. Warm colors tend to make you think of sunlight

and warmth.


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.


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.Ar.A.Purushothaman Arumugam M.Arch., CA, AIIA, Principal Architect - D2 Studios.

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.

Colors red yellow and green create a harmonious design, regardless of

whether this combination fits into a technical formula for color harmony.


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.
