3D Design Chapter 9 Flashcards
refracted light
The bands of color seen when white light is passed through a prism.
visible spectrum
The humanly perceptible bands of colored light created when white light passes through a prism.
reflected light
The light waves that bounce back to our eye from a surface rather than being absorbed into it. These reflected waves determine what we call the “color” of the object.
pigments
A powder that is the coloring ingredient for pain or other color media.
subtractive color mixing
Mixing of pigments, producing a slightly darker value since each pigment subtracts its energy from the light reflected by the mixture.
tint
A very light value of a hue.
shade
A dark value of a hue.
additive color mixing
Mixtures of light to create colors, called “additive” since each colored light ads its energy to the mixture, raising its value slightly.
optical color mixture
Colors mixed visually, as when hues are closely juxtaposed in apace or when transparent layers of different colors are overlaid.
hue
The characteristic of color identified by color names, such as red and blue. It corresponds to a particular wavelength within the spectrum of visible light.
color wheel
A two-dimensional circular model of relationships among hues.
primary colors
In color theory, those basic hues from which all other hues can be mixed. Different color theories suggest different primaries. In traditional color theory about pigment mixtures, the primary colors are red, yellow, and blue.
secondary colors
In color theory, the hues created by mixing two primary colors together.
tertiaries colors
In color theory, the hues created when a primary and a secondary color are mixed.
saturation (chroma or intensity)
A measure of the relative purity and brightness or grayness of a color; also called “chroma” or “intensity.”
complementary colors
Hues that are opposite each other on a color wheel. When mixed, they gray or neutralize each other; when juxtaposed, they intensify each other.
neutrals
Colors of very low saturation, approaching grays.
value
Degree of lightness or darkness.
Munsell’s color system
A three-dimensional model which can be used as an instrument of measuring and naming colors.
simultaneous contrast
The principle that the juxtaposition of two colors exaggerates their differences and reduces their similarities.
local color
The natural color of an object.
encaustic
A method of painting with pigment-bearing hot wax.
polychromed
Multicolored.
warm colors
Red, orange, and yellow hues.
cool colors
Hues in the green and blue range.
atmospheric perspective
Things seen at a distance have less value contrast and less distinct edges than things seen nearby.
monochromatic
A color scheme using closely related colors derived from a single hue but perhaps varying in value and saturation.
analogous colors
Hues lying next to each other on a color wheel, sometimes used together in color schemes.
double-complementary
Two adjacent hues and their complements.
split-complementary
One hue plus the hues on either side of its complement.
triad
Three hues equidistant from each other on the color wheel.
tetrad
Any four hues that are equidistant on the color wheel.
