Variables in Color Perception

Picture the color red

4 Variables in Color Perception:

1. LIGHT in which colored object is seen.

(temperature, season, time of day….)

2. OTHER COLORS surrounding a Color

3. SIZE of the Color

4. SURFACE on which color exists

Lighting indoors

A single uniform color

on a 3D form

lends itself to many

value changes because

of the way light interacts

with the surface.

Color Interaction & Simultaneous Contrast

Color interaction colors appear to be visually different in different contexts

Color Interaction: Colors appear to be visually different in different contexts.


Picture the color red

Simultaneous Contrast

The way in which two different colors affect each other—how one color can change how we perceive the tone and hue of another when placed side by side.

The colors themselves don’t actually change,

but we see them as altered.

3 Principles of Color Interaction

1. Light/DarkContrast

2. Complementary Reaction or Effect

3. Subtraction

3 properties of color

3 Properties of Color

  • Value

  • Hue

  • Intensity

3 properties of color1

3 Properties of Color

  • Value

V a l u e


  • lightness or darkness of a color

  • All colors (including black, white, non-chromatic grays) have value

  • If you take a black and white photograph of a full color painting, its valuerelationships are made visible, exclusive of its other two structural components. (Neither hue nor intensity is readable in a black and white photograph)

Value con trast


  • Varies infinitely. The most extreme contrast is between black & white.

  • A minor value contrast would be two values next to each other on our value scale.

    (There are an infinite number of grays between black and white,

    so we’re actually creating a very small sampling)

Achromatic scale aka value scale or grayscale
