Ch 13 Color Theory Flashcards
the progressive arrangement of colors (ROY G BIV) when a beam of light is broken down into component colors. We perceive color due to absorption or reflection of light off teh objects we are looking at
spectrum
colored object absorbs rays of light which illuminate it while others are reflected
absorption
the return of light from a surface
reflection
the property of a color by which it is distinguished from another. the word used to describe it such as red or yellow
hue
the lightness or darkness of a color; light value is high while dark value is low
Value
a hue into which various quantities of white are mixed
tint
a hue into which various quantities of black are mixed
shade
the amount of strength a color has; teh degree of purity of the brightness or dullness; amount of hue a color possesses
intensity (chroma)
a hue mixed with either a small quantity of gray or the complements of the hue, resulting in a dulling of the hue, making it more neutral and less intense
tone
a color not found in the visible spectrum; a neutral color such as white, black, gray
achromatic color
variations of one hue; tint tones and shades of one hue
monochromatic hue
a circle in which the primary,secondary, and intermediate hues are arranged in orderly intervals
color wheel
three hues that can be combined to make all other hues; cannot be produced by mixture of other hues;
RED-YELLOW-BLUE
Primary Hues
equal mixtures of two primary hues;
ORANGE-GREEN-PURPLE
Secondary Hues
equal mixtures of a primary and secondary color
Intermediate Hues
the mixture of two secondary colors or an unbalanced mixture of complements with the warm hue predominant
Tertiary Hue
colors directly opposite on the color wheel; when seen together present vivid contrasts; any two hues which by mixture produces gray
Complements
variations (tint,tones, and shades) of one hue
Monochromatic Color
two or more hues that have the same hue in common; adjacent to each other on the color wheel
analogous color
simultaneous contrasts; any two hues placed side by side or one hue superimposed upon the other
juxtaposition
visual impression remaining after a stimulus is removed
after image
a color that is characterized by long wavelenths; makes objects appear closer and larger and reflects warmth; orange
warm hue
a color that is characterized by short wavelenght; makes object appear to recede and impression of coldness
cool hues
that light produced by electric current running through a filament bulb; high in yellow
incandescent light
a long, tubular bulb where phosphors changes the electric current into light
fluorescent light
refers to the color of the illumination given off by the bulb
hue
refers to the brightness of the illumination
chroma
a visual aspect indicating the vividness of the hue in the degree of difference from a gray of the same lightness
saturation
a process of mixing colored lights on a surface whereby teh wavelenths of each are combined; adding of two or more lights together to create another light
additive method
