Prang System

Pigment color theory that employs the color wheel is the

indigo

a blue dye obtained from certain plants or made synthetically, usually from aniline dyes; a deep violet blue designated by Newton as one of the seven prismatic colors.

scarlet

a bright red color inclining toward orange

Color Wheel

a circle in which the primary, secondary, and intermediate hues are arranged in orderly intervals.

Purple

a color between blue and red; a secondary hue of pigments

Chromatic Color

a color having hue; a color of the visible spectrum.

achromatic colors

a color not found in the visible spectrum

Warm hue

a color which appears in the spectral band, characterized by long wave lengths; a color which makes an object appear closer and larger; a color which reflects warmth; i.e. red, orange, yellow and other colors in which they predominate.

overtone

a coloring modified by an overlying color; a color which visibly predominates more than general coloring; a wash.

Raspberry

a dark purplish-red color

Tones

a hue mixed with either a small quantity of gray or the complement of the hue, resulting in dulling the hue.

Tints

a hue which various quantities of white are mixed.

gray

a neutral, achromatic color resulting from the mixture of black and white pigments; a color resulting from the mixture of complementary pigmentary hues in equal quantities.

Professional portrait

a photograph or painting in which the subject has been posed and lightened flatteringly by a professional photographer or artist.

Intermediate color (hue)

a pigmentary hue produced by mixing, in equal quantities, a primary hue with its adjacent secondary hue on the color wheel.

Additive method

a process of mixing colored lights on a surface on which the wave lengths of each are combined; adding two or more colored lights together to create another color of light.

white light

a ray of light which contains all the hues of the visible spectrum, in such proportion that the light appears colorless or "natural"; as daylight or sunlight.

magenta

a red-purple or purplish-red. (e.g., a product of red and blue illumination projected on the same area).

highlight

a surface lying at right angles to the source of illumination which reflects the maximum amount of light; the brighter part

Saturation

a visual aspect indicating the vividness of the hue in the degree of difference from a gray of the same lightness.

Color

a visual sensation perceived by the eye and the mind due to the activity and vibration of light.

olive

a yellow-tan of medium value with a greenish tinge.

black

an achromatic color; the absence of all color in pigmentation

ROYGBIV

an acronym for the spectrum of light

Complementary Color

any two colors that combine to form white light

Juxtaposition

any two hues seen together which modify each other in the direction of their complements.

Cool Hue

blue, green, purple, or any intermediate pigmentary hue in which they predominate; a receding hue which creates the illusion of distance from the observer; a color of short wave lengths.

Chroma (Intensity)

brightness or dullness of a color.

brilliance

brightness; in colored illumination, the quantity of illumination passing through a color transparency.

vivid

brilliance; intensely bright color(s).

incandescent

brilliant; giving off heat or light

bronze

brown or copper-like in coloration.

bleed

color which escapes at the edges of a mixture

colored filter

colored glass, gelatin, or other substances which transmit light of certain wave lengths while absorbing the others.

radiant energy

energy traveling through space in the form of electromagnetic waves of various lengths

Secondary Color (hue)

equal mixture of two primary light colors that will produce pigmentary hues (orange, green and purple)

intense

existing in a high degree of brilliance; vivid

Shades

hue into which various quantities of black are mixed; the darkened hue.

Colored lighting

illumination of an identifiable hue

Analogous Color

in color harmony, two or more hues which have the same hue in common.

Three-quarter view

in reference to a photograph, a view which reveals the fullness of the cheeks.

Saturation

intensity of color

ultraviolet

invisible rays of the spectrum lying outside the violet end of the visible spectrum.

flourescent light

light that glows when an electric current causes ultraviolet waves to strike a coating inside a tube

illumination

lighting or light

subdued

lowered in intensity or strength; reduced in fullness or color; muted

Color Rendering Index (CRI)

measurement showing effect of a light source on the color of objects based on a 0 to 100 scale

subtractive method

method of diminishing the wave lengths of light by superimposing two or more color transparencies over the same light source; the light is gradually reduced by absorption of colors in the light.

primary colors

one of three pigmentary hues (red, yellow, and blue) which can be combined to make all other hues; in light color theory the hues red, blue and green can be combined to make all other hues.

Carmine

purple-red in coloration; (aka crimson)

Profile View

shows an object as though you were looking at it from the side

shadow

surfaces which do not lie at right angles to the source of illumination or are obscured by other surfaces and which reflect little or no light

Weight

the aspect of physical heaviness associated with different colors.

Conversion

the color of an object being changed or completely destroyed when one color of illumination strikes an object of a completely different color.

white

the color of pure snow; the color reflecting to the eye all of the rays of the spectrum combined; the opposite of black; an achromatic color; a neutral color.

Brown

the color of tanned leather

Vividity

the degree of brillance

orange

the hue obtained from the mixture of red and yellow; a secondary color of pigments.

green

the hue resulting from the mixture of yellow and blue pigments in equal quantities; one of three secondary pigmentary hues

tertiary colors

the hue which results from the mixture of two secondary pigmentary hues or an unbalanced proportion of complements with the warm hue or coll hue predominating.

value

the lightness or darkness of a hue

Rods of eyes

the long, rod-shaped sensory bodies of the retina of the eye responsive to light but not color.

Infrared

the part of the invisible spectrum adjacent to the red end of the visible spectrum

emphasis

the process

Absorption

the process of taking in, as in a colored object which absorbs certain rays of light and reflects other rays giving the object its recognizable color. (e.g. An Apple is called red if the red rays are reflected and the other rays in the light are absorbed.

hue

the property of a color by which it is distinguished from other colors.

Funeral lighting

the quality and quantity of illumination used for presentation of casketed remains

Force

the quality of a color to draw attention by means of its intensity or "advancing" characteristics.

Reflected (reflection)

the return of light waves from surfaces; the bending or folding back of a part upon itself.

intensify

to become more brilliant or more vivid in color.

Mute

to reduce the intensity of a color by the addition of another color

light

to shine; a form of electromagnetic radiation that acts upon the retina of the eye to make sight possible

blanch

to whiten by removing color; to make pale

Monochromatic hues

variations of one hue; tints, tones, and shades of one hue.

spectrum

visible band; the original standard of color; the progressive arrangement of colors (ROYGBIV) seen when a beam of white light is broken down into its component colors.
