BASIC COLOR THEORY
Color theory encompasses a multitude of
definitions, concepts and design applications -
enough to fill several encyclopedias. However,
there are three basic categories of color theory
that are logical and useful : The color wheel,
color harmony, and the context of how colors
are used.
Color theories create a logical structure for
color. For example, if we have an assortment of
fruits and vegetables, we can organize them by
color and place them on a circle that shows
the colors in relation to each other.
The Color Wheel
A color circle, based on red, yellow and blue,
is traditional in the field of art. Sir Isaac
Newton developed the first circular diagram of
colors in 1666. Since then, scientists and
artists have studied and designed numerous
variations of this concept. Differences of opinion
about the validity of one format over another
continue to provoke debate. In reality, any color
circle or color wheel which presents a
logically arranged sequence of pure hues has merit.
There are also definitions (or categories) of
colors based on the color wheel. We begin with a
3-part color wheel.
- Primary Colors: Red, yellow and blue
In traditional color theory (used in paint and
pigments), primary colors are the 3 pigment
colors that can not be mixed or formed by any
combination of other colors. All other colors
are derived from these 3 hues.
- Secondary Colors: Green, orange and purple
These are the colors formed by mixing the
primary colors.
The color systems used by scientists and
artists are entirely different. An artist will mix blue and yellow paint to get
a shade of green; a scientist will mix green and red light to create yellow.
The printed page in a magazine is yet another system.
It's important to define the two different
kinds of color that we see in the world as the first step in understanding
color systems. First, there's the color you can touch, such as the skin of an
apple or a painted wall. These colors are part of the surface of an object.
Next, there's the color you can't touch, such as a beam of red light and the
colors produced by your computer monitor. Colors generated by light are part of
one color system. The tangible colors which are on the surface of objects or on
the printed page are another color system.
The following illustrations and descriptions
define the different color systems.
1. Additive Color System
Red - Green - Blue (RGB)
Red - Green - Blue (RGB)
Scientists recognize the light primaries of
red, green and blue. When combined, red and green light rays produce yellow,
blue and green produce cyan, red and blue produce magenta. Red, green and blue
mix to create white (light). Link to How the Eye Sees Color for more information on the
"additive" definition of light. This color model is used in computer
monitors, television sets, and theater.
2. Subtractive Color System
Red - Yellow - Blue
Red - Yellow - Blue
Primary Colors

Secondary Colors
|
Tertiary Colors
|
Most artists recognize red, yellow and blue as
the 3 basic primary colors. These primaries are the pure colors which can not
be created by mixing any other colors. Secondary hues are the result of mixing
any of the two primaries. Tertiary colors result from mixing the secondary
hues.
In subtractive color theory, all colors mix to
yield black. Link to "How the Eye Sees Color" for more information about
why this color system is subtractive.
3. The CMYK Color System
Cyan - Magenta - Yellow - Black
Cyan - Magenta - Yellow - Black
In the print industry, cyan, magenta, yellow
and black are used as the primary colors. When you mix all the colors, the
result is gray. If you look at a printed page with a magnifying glass you might
see something like the illustration below.
