adjacency
The affect of surrounding areas on color vision. A given color area generally looks brighter if the surroundings are dark, and a given color looks more saturated if surrounded by complementary color. This contrast enhancement relates to the general importance of borders in perception. It is primarily the color area borders that signal the mind.

amplitude
The maximum absolute value reached by a waveform.

ANSI
Acronym for American National Standards Institute. A voluntary, nonprofit organization of US business and industry groups formed in 1918 for the development of trade and communication standards. ANSI is the American representative of the International Standards Organization (ISO).

CMYK
Acronym for cyan-magenta-yellow-black. A color model that is similar to the CMY color model but produces black with a separate black component rather than by adding 100 percent of cyan, magenta, and yellow. Note: K stands for key plate, the black printing plate. See also CMY.

configuration
n. 1. a. Arrangement of parts or elements. b. The form, as of a figure, determined by the arrangement of its parts or elements. 2. Psychology Gestalt.

color constancy
The tendency to perceive inaccurate nature-specific and object-specific colors as true is color constancy. Some examples of these 'memory' colors are: eggshell white, fire-engine red, lemon yellow, and sky blue. Skin tones also come under color constancy. When a printed image is viewed individually the color looks correct, when we compare the accurate flesh tone to the inaccurate color then the color difference becomes evident. In addition to these other aspects, the eye is most sensitive to colors in the middle of the spectrum. Given equally intense colors, midspectrum colors such as green appear brighter than the endspectrum colors of red and blue.

color space
In an attempt to index colors in relation to one another it is common to rely upon a triaxial system. This section will address the various color spaces in common use today. We use the term 'space' because color data occur in three dimensions. Science and industry require precise color definition and classification. Words are imprecise to distinguish and describe color. For example, some of the few words that exclusively name colors are: white, black, gray, yellow, red, violet, blue, green, brown, and others. Many colors require compound names, quantifiers, and suffixes to differentiate colors. Examples are yellow-green, light green, greenish, and so forth.

connotation
n. 1. The act or process of connoting. 2a. An idea or meaning suggested by or associated with a word or thing. b. The set of associations implied by a word in addition to its literal meaning. 3. Logic The set of attributes constituting the meaning of a term; intension. adj. connotative.

Something, such as a feeling, thought, or idea, associated in one's mind or imagination with a specific person or thing: association, connection, suggestion.
      Compare DENOTATION. In a widespread literary usage, the denotation of a word is its primary signification or reference; its connotation is the range of secondary of associated significations and feelings which it commonly suggests or implies. The connotation of a word is only a potential range of secondary significations; which part of these connations are evoked depends on the way the word is used in a particular context. [Abrams, 1999]

If the cutting plane be produced so as to cut the opposite cone, another curve will be formed, which is also an hyperbola. Both curves are regarded as branches of the same hyperbola.
