Basic Color Principles

When a beam of white light is passed through a

prism, a spectrum of the entire range of pure colors

visible to the naked eye is formed.



The Three Dimensions of Color

• Hue

•

Value• Chroma



Hue

• Hue identifies a color by name. Every color

falls into a definite hue category as indicated

by the spectrum color name on the color

wheel.



Value

• White added to a

hue creates a tint.

• Gray added to a hue

creates a tone.

•

Black added to ahue creates a shade.

Value is the lightness or darkness of a hue achieved by adding white, gray, or black.



Chroma• Chroma refers to the degree of intensity, strength,

saturation, or purity of a color. Purity of a color

refers to its freedom from white, black, or gray.



Primary Colors

• Red, blue, and

yellow comprise the

three primary colors.

• These three colorscan approximate,

through selective

mixture, all of the

other colors.



Secondary Colors

• Orange, violet,

and green are the

secondary colors.

• Each is placed

between the two

primaries that are

mixed to produce it.



Primary & Secondary Colors



Color Harmony

• Complementary

• Split Complementary

• Triadic

• Analogous

•Monochromatic



Complementary

• Complementary color harmony features colorsdirectly opposite on the color wheel.



Split Complementary

•

Combining one color with two colors on either side of its direct complement results in a split complementary.



Triadic

•

Triadic color harmony involves three colorsequally spaced on the color wheel.



Analogous

• Analogous colors consist of related colors that

are adjacent on the color wheel.

• They usually include only one primary color.

• Analogous color harmony allows one color todominate and others to enhance.



Monochromatic

• Monochromatic color represents a harmonyarrived at through variation in the value and

intensity dimensions of a single color.



Color Balance• Any color which dominates its immediate

environment in hue, intensity or value will over balance a color or colors of lesser contrast andtend to divert attention from the composition.



Warm Colors

• Warm, or advancing colors, are those thatresemble fire and heat. Red, red-violet, red-orange, and yellow-orange are examples of warm colors.

• Warm colors appear closer and are moreeye catching than cool colors.



Cool Colors

•

Cool, or receding colors, are associatedwith peace and calm. Blue, blue-green, and blue-violets represent cool colors.

• Cool colors in a composition tend to

visually recede and look smaller. They arenot easily seen from a distance.
