Color and Color Theory Flashcards
all wavelengths of light absorbed
black
if all wavelengths of light reflected
white
lens refracts light to converge on retina; nerves transmit image
retina
nerve cells in retina; very sensitive to light and dark
rods of eye
nerve cells help to see light and color
cones of eye
where does color come from
ray of light source of all color
light broken down into colors of spectrum
components of white light
dispersion
ROYGBIV
primary colors
red
green
blue
mixtures will produce all other colors
primary colors
cannot be reproduced from mixtures of light colors
primary colors
red + blue + green =
white light
color obtained by emitted light; associated with tv and computer displays
additive colors
primary additive colors
R B G
secondary additive colors
cyan
yellow
magenta
3 scientific principles
dispersion
reflection
absorption
return of light waves from surface
reflection
process of taking in
absorption
substances that can be ground down into fine powder and used for adding color to dyes and paints
pigments
originally derived from animal, mineral, and vegetables sources
pigments
purple pigment from
shell fish
red dye pigment from
dried body of scale insects
basic tool when working with pigmentary colors
color wheel
based on standard color theory known as prang system
color wheel
color associated with subtraction of light
subtractive color
used in pigments for paints, inks, fabrics, etc
subtractive color
primary subtractive colors
R Y B
secondary subtractive colors
G P O
what subtractive primary colors combined produce
black
___ hues in spectrum of color on color wheel/prang syst.
12
color wheel/prang syst. divided into ___ categories
3
primary hues
R Y B
cannot be combined from mixing any colors together (color wheel)
primary hues
secondary hues
G V O
made by combining primary hues
secondary hues
intermediate hues
yellow-green blue-green blue-violet red-violet red-orange yellow-orange
made by combining primary hue and secondary hue
intermediate hue
mixture of 2 secondary pigmentary hues or unbalanced proportion of complements with the warm hue/cool hue predominating
tertiary hue
all shades and tints of one color
monochromatic
3 categories of hues on color wheel
primary, secondary, intermediate hues
color seen
hue
lightness or darkness of color
value
brightness or intensity of color
chroma
defines color by name
hue
lightness or darkness by adding white, black or gray
value
add white to hue adds ?
tint
add gray to hue adds ?
tone
add black to hue adds ?
shade
degree of intensity, strength, saturation or purity of color
chroma
freedom from white, black or gray
purity
2 or more colors that are next to each other on color wheel
analogous
analogous colors
red, red-orange, orange, yellow-orange/ blue-green, blue, blue-violet
color having hue; 1 related to color of visible light spectrum
chromatic color
color not found in visible light spectrum; have no hue
achromatic color
psychological; visual impression remaining after stimulus has been removed
after image
any 2 hues seen together which modify each other in the direction of their complements
