ColorDerives from the spectrum of light

(distribution of light energy versus

wavelength) interacting in the eye with the

spectral sensitivities of the light receptors.

Shade and tintare terms that refer to a variation of a hue.

A hue produced by

the addition of white.A hue produced

by the addition of black.

Subtractive Color. When we mix colors using paint, or through theprinting process, we are using the subtractive color method.

Subtractive color mixing means that one begins with white and ends

with black; as one adds color, the result gets darker and tends toblack.

Additive Color. If we are working on a computer, the colors we see onthe screen are created with light using the additive color method.Additive color mixing begins with black and ends with white; as morecolor is added, the result is lighter and tends to white.

Primary Colors

The next aspect to the color wheel is creating the

secondary colors. These colors are placed in

triangles above the corresponding primary colorcombination. This system of color mixing is known as

the subtractive process, because the resultingsecondary color subtracts or absorbs even more

waves from the white light than the first color did.


15/57

The secondary colors are:

orange (mix red + yellow)

green (mix yellow + blue)

violet (mix blue + red)

These secondary colors are also known as

The final step to creating the 12 step color wheel will be to create a ring around the

newly formed primary and secondary color form. Divided into 12 equal segments,

the primary and secondary colors shall be repeated to their corresponding segment

within the surrounding ring. This will leave a blank segment between every two

colors. In these blank segments the tertiary colorswill be created.

Secondary Colors


16/57

The are: yellow-orange, red-orange, red-

violet, blue violet, blue-green, and yellow-green.

The sequence of colors on the color wheel should

resemble that of the rainbow.

We can now use our color wheel as the basis to

understanding color and color combination techniques.

Tertiary Colors

In color theory, a is the choice of

colors used in design for a range of media.

TYPESOF COLOR SCHEME

Analogous:Colors that contain a common hue and are

found next to each other on the color

wheel, e.g., violet, red-violet, and redcreate a sense of harmony. Remember

adjoining colors on the wheel are similar

and tend to blend together. They are

effective at showing depth.


19/57


Monochromatic:One color. A monochromatic color scheme

uses only one hue (color) and all values

(shades or tints) of it for a unifying and

harmonious effect.


20/57


Neutral colors:Contain equal parts of each of the

three primary colors - black, white, gray, and

sometimes brown are considered "neutral".

When neutrals are added to a color only the

value changes, however; if you try to make

a color darker by adding a darker color to it

the color (hue) changes.


21/57


Warm colors:Suggest warmth and seem to

move toward the viewer and appear closer,

e.g., red and orange are the colors of fire.


22/57


Cool colors:Suggest coolness and seem to

recede from a viewer and fall back, e.g.,blue and green are the colors of water and

trees).


23/57


Complementary:Two colors opposite one another on the

color wheel, e.g., blue and orange, yellow and purple,

red and green.

When a pair of high intensitycomplements are placed side by side, they seem to

vibrate and draw attention to the element Not all color

schemes, based on complementary colors are loud

and demanding -- if the hues are of low-intensity the

contrast is not too harsh.

Intensity can only be altered by mixing a

color with its complement, which has the effect of

visually neutralizing the color. Changing the values of

the hues, adding black or white, will soften the effect.


24/57


Triad:A color triad is composed of three

colors spaced an equal distance apart on the

color wheel. The contrast between triad colors

is not as strong as that between complements..

Primary - red, yellow, and blue


25/57


Triad:Secondary - by mixing two primary colors,


26/57


Triad:Intermediate - colors are created by mixing aprimary and a secondary: Red-orange, yellow-

orange, yellow-green, blue-green, blue-purple,and red-purple.


27/57


Triad:Split complements - the combination of one

hue plus the hues on each side of its

complement. This is easier to work with than astraight complementary scheme. It offers more

variety, e.g., red-orange, blue, and green.


28/57


Triad:Double complementary - two adjacent huesand their opposites. It uses four colors arranged

into two complementary color pairs. Thisscheme is hard to harmonize; if all four colors

are used in equal amounts, the scheme may

look unbalanced, so you should choose a color

to be dominant or subdue the colors.

SPATIAL EFFECTS

Hues that are lighter at maximum saturation (yellows, oranges) appear larger

than those that are darker at maximum saturation (e.g., blues and purples).

Saturation is the relative brilliance or vibrancy of a color. The more saturated a

color, the less black it contains.


31/57

BALANCEAND PROPORTION

Generally speaking, less saturated or busily detailed areas will draw attention

and therefore seem to carry more weight than highly saturated or visually

simpler areas.


32/57

EMPHASIS

An area in a work of art that attracts the viewers attention first. The element

noticed first is called dominant; the elements noticed later are called

subordinate.


33/57

UNITY

Allows the viewer to see a combination of elements, principles, and media as a

whole. Unity is created by harmony, simplicity, repetition, proximity, and

continuation. For example, you could use the repetition of a color scheme to

unify a composition.


34/57

MOVEMENT

Color can create a sense of movement. When the values in a work jump quickly from very

high-key to very low-key, a feeling of excitement and movement is created. When all of

the values are close together the work seems much calmer. When you want to create

movement with color remember to use values of pure hues as well as those of tints and

shades. Movement creates the illusion of action or physical change in position.


35/57

RHYTHM

The use of repeated elements to create the illusion of movement. Visual

rhythm is perceived through the eyes, and is created by repeated positive

spaces separated by negative spaces. There are five types of rhythm: random,

regular, alternating, flowing, and progressive.

Physiological Effects

Mystics have long held we emanate a colored glow, or aura,which is thought to effect the state of a person's health and

spirituality. Today, chromotherapy is used to heal with colors. Thisform of treatment dates back thousands of years to the ancient"color halls" of Egypt, China, and India. A more prominent use ofcolor therapy occurs in environmental design (the effect of coloron health and behavior).

Emotional Effects

The actual emotional effect of a specific color in an artwork

depends partly on its surroundings and partly on the ides

expressed by the work as a whole. To be surrounded by blue

lighting in an installation is quite different from seeing a small

area of blue in a larger color context. For many of us the

emotional effects of art may be difficult to articulate.


41/57

Local and Expressive Color

There are two opposite ways of using color in representational

art. At one extreme is the local color - the color that something

appears from nearby when viewed under average lighting

conditions. We think of the local color of a banana as yellow, for

example. At the other end of the extreme is the expressionistic use

of color, whereby artists use color to express an emotional rather

than a visual truth.


42/57

REDthe warmest and the most energetic color of the spectrum. Red is

associated with love thus it is he color of Valentine s Day. It couldalso mean danger which is why most warning labels, emergency exit

Color serves many aestheticpurposes in the design of thebuilding, namely:

It creates an atmosphere

It suggests either unity or diversityIt expresses character of materialsIt defines formIt affects proportionsIt brings out scaleIt gives a sense of weightIt projects value in physical propertiesIt brings out composition/organization of structures.
