| name | color-theory |
| description | Color theory principles for art education. Covers the three color properties (hue, saturation, value), color mixing systems (subtractive and additive), color relationships (complementary, analogous, triadic, split-complementary), color temperature, simultaneous contrast and the relativity of color perception, and practical palette construction. Use when analyzing color in artworks, planning color schemes, understanding optical phenomena in painting, or investigating Albers's Interaction of Color experiments. |

Color Theory
Color is the most relative medium in art. A single hue appears warm or cool, bright or dull, advancing or receding depending entirely on the colors surrounding it. Josef Albers demonstrated this rigorously in Interaction of Color (1963): the same gray rectangle placed on a black background appears lighter than the identical gray on a white background. This skill covers the fundamental properties of color, mixing systems, relational color schemes, and the perceptual phenomena that make color theory essential to every visual art discipline.

Color Properties
Every color has three independently variable properties. Mastering color requires the ability to identify and manipulate each property independently.
| Property | Definition | Range |
|---|
| Hue | The color's position on the spectrum (red, orange, yellow, green, blue, violet) | Circular -- wraps from violet back to red |
| Value | Lightness or darkness | White (highest) to black (lowest) |
| Saturation | Purity or intensity -- distance from neutral gray | Full saturation (pure hue) to zero saturation (gray) |
Hue
Hue is what most people mean when they say "color." The traditional painter's color wheel arranges hues in a circle: red, red-orange, orange, yellow-orange, yellow, yellow-green, green, blue-green, blue, blue-violet, violet, red-violet. The circle is useful because relationships between hues (complementary, analogous, triadic) are geometric positions on this circle.
Value
Value is the most structurally important property. A painting with correct values and wrong hues will read correctly from across a room. A painting with correct hues and wrong values will look flat and confusing. Value is independent of hue -- every hue has a natural value (yellow is inherently light, violet is inherently dark), and mastering color means learning to push hues above or below their natural value when the composition demands it.
Saturation
Saturation describes how pure a color is. Cadmium red out of the tube is near full saturation. Adding its complement (green) or adding gray progressively desaturates it toward a neutral brownish gray. Most natural environments are dominated by low-saturation colors, with high-saturation accents. Beginners tend to use too much saturation everywhere, producing garish results.
