| Read the section on Colour in the text—pages 52 through 65. Study the vocabulary and be able to define the terms. |

| Primary colors | >the colors you can not make by mixing. In subtractive color, they are red, yellow and blue. In additive, they are red, green and blue. In printing, they are cyan, magenta, yellow and black (cymk). | ||||||||||||||||
| Secondary colors | >the colors that are the result of mixing even parts of two primaries. Red and blue make purple, etc. | ||||||||||||||||
| Complementary colors | >colors that are opposites. They reside on opposite sides of the color wheel. Every color has a complement | ||||||||||||||||
| Tertiary colors | >colors that sit side by side on the color wheel. They are the intermediate gradations between colors | ||||||||||||||||
| Analogous colors | >like tertiary but relating to specific colors. The colors that are analogous to orange are the ones that sit to either side of orange on the color wheel. | ||||||||||||||||
| additive color | >refers to mixing colored light to create other colors. Mix all three primary colors to create white light. | ||||||||||||||||
| subtractive color | >refers to mixing pigments or paint to create other colors. Mixing all three primaries results in black. | ||||||||||||||||
| Hue | >determined by wavelength in the spectrum of color, distinguishing one color from another. Usually refers to the name of a color. Red is a hue, bluegreen is a hue. D | ||||||||||||||||
| Value | >refers to the quality of lightness or darkness of a color. The lightest being yellow and the darkest being purple. Each color's value can be gauged compared to a gradation from white to black. | ||||||||||||||||
| Saturation | >the relative brightness or intensity of a color. The color wheel is made up of highly saturated colors. which can be desaturated by mixing it with its complement. | ||||||||||||||||
| Simultaneous Contrast | >an effect created by the action of the cones and rods in the retina of the eye in response to light waves. Like when a flash bulb goes off we see the afterimage of the white light, which is a black spot. The same phenomena occurs with intense stimulation by any of the hues. The resulting after image is the complement or the color on the opposite side of the color wheel. But when you are intensely stimulated by any color, all the adjacent or neighboring colors will be influenced by the complement. A gray surrounded by red will appear more like green. | ||||||||||||||||
| Successive Contrast | >related to simultaneous contrast except that the effect occurs not to adjacent colors but to all colors perceived immediately after intense stimulation by a color. (most like the afterimage effect.) It is also related to the experience we have of bright light when we leave a darkened room and go outside into the sunlight. Because our eyes respond to darkness with the opposite (light) the double dose of light is too much for us. It takes some time for our eyes to adjust. | ||||||||||||||||
| Optical mixing | >refers to a phenomena of perception where marks or stripes of one color are interspersed with those of another color, from a distance our eyes with see them as mixed into a third color, the color attained by mixing the two colors. If someone wears a blue and yellow striped shirt, we will see the shirt as green when viewed from a distance. (also called the Bezold Effect) | ||||||||||||||||
| color temperature (warm, cold) | >a pervasive metaphor: colors in a context with other colors will be understood to be warmer or cooler than the others. Blues, greens and purples tend to be read as cool colors. Reds, yellows and oranges are seen as warm colors. But some reds are warmer than others. And that goes for all the colors. | ||||||||||||||||
| symbolic color | >colors have meaning relative to cultures. For example, “blues are for boys and pinks are for girls.” | ||||||||||||||||
