Color characteristics colorconstancy-A psychological compensation for changes in light when observing a color. A viewer interprets the color to be the same under various light conditions.
constancyeffect-An aspect of human perception that allows us to see size or color or form as consistent even if circumstances change appearances.
Properties of color
Hue- A property of color defined by distinctions within the visual spectrum or color wheel. “Red,” “blue,” “yellow,” and “green” are examples of hue names.
Value- A measure of relative lightness or darkness.
Saturation- The saturation of hue perceived in a color.
3 dimensions of color perception- Mixtures of complements on this wheel will more closely produce neutrals (when tested as light mixtures, for example), and the positions of the colors are more useful in predicting paint mixtures as well.
Intensity- The saturation of hue perceived in a color.
Complementary colors- A color scheme incorporating opposite hues on the color wheel. Complementary colors accentuate each other in juxtaposition and neutralize each other in mixture.
Palettes- spectrum of color used as artist’s tools, either traditional or electronic
Visual color mixing- Placing small units of color side by side so that the eye perceives the mixture rather than the individual component colors.
Cool colors- A color closer to blue on the color wheel.
Warm colors- A color closer to the yellow-to-red side of the color wheel.
Color dominance- Color is very often the means chosen to provide this emphasis—color is probably the most direct device to use.
Achieving balance with color- regain balance by adding and equally weighed aspect.
Spatial properties of color
- atmospheric perspective-the earths atmosphere disperses the shorter wavelengths of blue coloring the sky and objects that recede into the atmosphere. As the object recede any brilliance of color becomes more neutral, finally seeming gray-blue. Value and color contrast are more pronounced in foreground and subtle in the distance.
Monochromatic- A color scheme using only one hue with varying degrees of value or intensity.
Analogous- A color scheme that combines several hues located next to each other on the color wheel.
Triadic- A color scheme involving three equally spaced colors on the color wheel.
Color discords- A perception of dissonance in a color relationship.
Vibrating colors- Colors that create a flickering effect at their border. This effect usually depends on an equal value relationship and strong hue contrast.
Local color- The identifying color perceived in ordinary daylight. The color we know an object to be.
Arbitrary color- In arbitrary color, the color choices are subjective rather than based on the colors seen in nature. The artist selects colors for design, aesthetic, or emotional reasons.
Emotional color- A subjective approach to color use to elicit an emotional response in the viewer.
Color symbolism- Employing color to signify human character traits or concepts.
