Definition
| Grays that are created by mixing black and white. Achromatic grays have no coloration when seen against a white background. Black and white are also achromatic. |
|
|
Term
|
Definition
| A color mixing system in which combinations of different wavelengths of projected light create visual sensations of color. Additive color primaries are red, green, and blue-violet; when they are combined, the result is white light (Theater). |

Term
|
Definition
| Occurs after staring at an area of intense color for a certain amount of time and then quickly glancing away toward a white surface where the complimentary color seems to appear. |

Definition
| Hues that lie adjacent to each other. |
|
|
Term
|
Definition
| An irregularity; a deviation from a norm. An anomalous color is one that breaks sharply with the dominant tonal quality established by a group of colors. |
|

Term
|
Definition
| The vehicle in paint, such as oil or acrylic resin (polymer), in which pigment is suspended. |
|
|
Term
|
Definition
| Tones, tints, or shades that combine qualities of two distinctly different colors, and act to soften those differences when placed near them in a composition. |
|
|
Term
| Broken Color (Broken Value) |
|
Definition
| An effect when paint is applied lightly, with a dry-brush effect, over a dried layer of paint, allowing some of the underneath color (value) to show through. Typically achieved through scumbling. |
|
|
Term
|
Definition
| Subtle colors that result from considerably lowering the saturation level of prismatic colors. Chromatic grays weakly exhibit the distinguishing quality of the hue family to which they belong. |
|
|
Term
|
Definition
| Hues that lie directly opposite each other on the color wheel. |

Definition
| Color sensitive cells in the retina. |
|
|
Term
|
Definition
| A color that appears to be closer to the blue-to-violet side of the color wheel. |
|
|
Term
|
Definition
| The result of the sub-division of the (subtractive) primary triad into three pairs, consisting of cool and warm versions of each hue. The use of co-primaries greatly extends the potential range of mixed colors. |
|
|
Term
|
Definition
| An illusion of transparency where a color of the overlapping area is darker in value than both colors that appear to overlap. The hue in a dark transparency blends the hues of the two parent colors. |
|
|
Term
|
Definition
| Similar to stamping. A painting technique in which one surface ("the decal") is painted and then pressed, while still wet, against the painting; when the decal is peeled away, some paint remains stuck to the painting in a pattern, often with unexpected qualities. |
|
|
Term
|
Definition
| A primary triad of chromatic grays (so called because of their resemblance to pigments found in nature, e.g., ochre and umbers). |
|
|
Term
|
Definition
| A thin layer of transparent color applied to the surface of a painting. |
|
|
Term
|
Definition
| A painting technique in which an artist presses a textured surface/object onto a wet canvas, producing an imprint. |
|
|
Term
|
Definition
| A graduated representation of the value continuum that is broken down into a finite number of steps, usually ten to twelve achromatic grays |
|
|
Term
|
Definition
| What an image is said to be when the colors in it are predominantly light in value. |
|
|
Term
|
Definition
| Refers to the wavelength of light as seen in the full color spectrum from red to violet. A hue is modified to create a variety of colors. EX: Hue = blue, colors = Prussian, Ultramarine, Cerulean, Cobalt, Indigo. |
|
|
Term
|
Definition
| A painting technique in which paint is applied in thick layers or strokes to create a rough three-dimensional paint surface. |
|
|
Term
|
Definition
| The light that seems to glow from within the color. |
|
|
Term
|
Definition
| The natural value of colors as they appear in the spectrum. EX: Spectral blue is darker in value than yellow. |
|
|
Term
|
Definition
| Not based on carbon chemistry, but instead are derived from natural minerals and ores. These materials are oxides, sulfides, and various salts of metallic elements. Most inorganic pigments offer relatively low chroma, low tinting strength, and a moderate to high degree of opacity. EX: Cadmium colors, Chromium colors, Titanium colors, Zinc white, and Yellow Ochre. |
|
|
Term
|
Definition
| The process in which two or more light waves of the same frequency interact to cancel each other out. |
|
|
Term
|
Definition
| The display of intense, shifting hues, as seen on the surface of soap bubbles or puddles of water with oil. |
|
|
Term
|
Definition
| The identifying color perceived in ordinary daylight. |
|
|
Term
|
Definition
| What an image is said to be when the colors in it are predominantly dark in value. |
|
|
Term
|
Definition
| The amount of light reflected from the surface of a color. Value is a measure of luminosity. |
|
|
Term
|
Definition
| An illusion of transparency where the value of the color at the overlap is halfway between that of the two parent colors. The hue of the overlapping area blends the hues of the two overlying colors equally. |
