Chapter 9: Perceiving color Flashcards
perception of color is associated with the:
physical property of wavelength
transparent objects are perceived as chromatic color created by _____________
selective transmission
mixing lights is a _____ color mixture
additive
mixing paints is a ________ color mixture
subtractive
the term for lights being physically different, but perceptually identical:
metamerism
the three types of color deficiency are:
monochromat, dichromat, and anomalous trichromat
a unilateral dichromat has ______ vision in one eye and _______ vision in the other
trichromatic, dichromatic
monochromatism results in perceiving what colors?
black, white, and grey
what is stated by the opponent-process theory of color vision?
color vision is caused by opposing responses generated by blue/yellow and red/green
color constancy refers to:
perceiving the colors of objects as being the same, even under changing illumination
chromatic adaptation is:
prolonged exposure to chromatic color
amount of light reaching the eye from an object is dependent on: (2)
illumination and reflectance
the ratio principle states:
as long as the ratio of reflectance of the object to reflectance of surrounding objects stays the same, perceived lightness will stay the same
reflectance edges are:
where the reflectance of two surfaces changes
illumination edges are:
where the lighting changes (creating shadows)
another term for chromatic color:
hue
value of color represents:
the light-to-dark dimension
saturation of color represents:
the amount of white in a hue
behavioural evidence for the trichromatic theory is present in:
color matching
the principle of univariance states:
absorption of a photon causes the same effect in all receptors, no matter what the wavelength is
the originally proposed color center:
V4
