Picture the color red…

Picture the color red…

Picture Coca-Cola red…

What red are you seeing now?

How many different reds do you perceive?

Richard Anuszkiewicz, All Things Do Live in Three, 1963 Acrylic on Masonite, 21” x 35”

Describe what you’re seeing…

Are these all Yellow Lemons?

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

4 Variables in Color Perception:

LIGHTING (indoors)

Daylight Incandescent Fluorescent

Claude Monet’s Poplars on the Epte

LIGHTING (outdoors): SEASON, TIME OF DAY, TEMPERATURE, LOCATION

OTHER COLORS

SIZE

SURFACE

Sculpture by: Maria Lewis, Shvetashvatara Upanishad, 1995Acrylic Paint on canvas, 29” x 29”

A single uniform coloron a 3D form lends itself to manyvalue changes because of the way light interactswith the surface.

Color Interaction & Simultaneous Contrast

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

VS.

Simultaneous ContrastThe 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.

Simultaneous Contrast: Light/Dark Contrast

LIGHT/DARK CONTRAST:Relativity of Color

Relativity of VALUE

3 Properties of Color

• Value• Hue

• Intensity

3 Properties of Color

• Value

VALUE• 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 value relationships are made visible, exclusive of its other two structural components. (Neither hue nor intensity is readable in a black and white photograph)

Value CONTRAST

• 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)

a = withoutchroma = color
