chapter 5 Flashcards
how does mixing color work?
light sources
pigments
light sources
objects that generate electromagnetic energy in the visible spectrum
pigments
objects that reflect light from light sources
subtractive color mixing
mixture of pigments- the wavelengths of the two pigments act like filters when they combine
additive color mixing
a mixture of lights- the wavelengths of the two lights add together to form a new color
what are the three different types of cones
S M L
rob NOTATION
each red, green, and blue part of a pixel are assigned to a value between 0 and 255
trichromatic theory of color vision
three types of photoreceptors help us discriminate colors
does the visible color spectrum ever stop?
no, it is continuous
basic color terms
single words that are used to describe a color- meaning is agreed upon by speakers of a language
culture relativism
the idea that basic perceptual experiences can be shaped by cultural history of the individual
color constancy
the same physical colors can be perceived differently depending on scene content and prior experience
color contrast illusion
a color perception effect in which the color of one region induces the opponent color in a neighboring region, increasing the contrast between two nearby colors
color/negative afterimages
we adapt to the colors that are viewed in short periods of time, when these colors are removed we see the opponent colors
color constancy
the tendency of a surface to appear the same color under a wife range of light sources
