Graded A+
Quiz: Functions of Color Perception
Ans: - color signals help us classify and identify objects
- color facilitates perceptual organization of elements into objects
- color vision may provide an evolutionary advantage in foraging for food.
Quiz: Perception of color is related to________.
Ans: - the wavelength of light
Quiz: visible spectrum
Ans: - the portion of the electromagnetic spectrum that we can see
- spans from 400 to 700 nm
Quiz: Wavelength
Ans: - the distance from the peak of one light or sound wave to the peak of
the next
- vary from the short blips of cosmic rays to the long pulses of radio
transmission
Quiz: Separating Various Wavelengths by Prism
Sunday, 02 March 2025
,Ans: - the light that appears white actually contains lights of many
wavelengths
- a glass prism can separate lights of different wavelengths because these
lights are bent at different angles inside the prism.
Quiz: Achromatic colors
Ans: - black, white, and grays
Quiz: Chromatic colors
Ans: - all the other hues besides black, white, and grays
Quiz: Saturation
Ans: - vividness of a color; the relative amount of whiteness in a chromatic
color
Quiz: Value
Ans: - the light-to-dark dimension of color
Quiz: Reflectance
Ans: - the percentage of light reflected from a surface
Quiz: Transmission
Examstudy - Stuvia US
,Ans: - the percentage of light transmitted through media (i.e. liquid)
Quiz: Reflectance curves
Ans: - the graphs showing the percentage of reflectance as a function of
wavelength
Quiz: Additive color mixture
Ans: - obtained by mixing lights
- superimposing blue and yellow lights leads to white
- i.e. spotlights, TV, computer screen
Quiz: Subtractive color mixture
Ans: - obtained by mixing paints with different pigments; additional
pigments reflect less wavelengths, leading to darker appearance
- mixing blue and yellow leads to green
- i.e. mixing paints, using filters repeatedly
Quiz: Trichromatic Theory of Color Vision
Ans: - proposed by Young and Helmholtz (1800s)
- three different receptor mechanisms are responsible for color vision
*Psychophysical evidence for trichromatic theory: color-matching
experiment
Examstudy - Stuvia US
, Quiz: 3 types of cones
Ans: - short-wavelength sensitive cones (S cones, blue)
- middle-wavelength sensitive cones (M cones, green)
- long-wavelength sensitive cones (L cones, red)
Quiz: Principle of Univariance
Ans: - individual receptors respond to light stimulus in only one dimension,
thus they cannot tell what the wavelength of the light is
Quiz: Color Matching Experiment
Ans: - observer adjusts the amount of lights of three wavelengths of a
comparison field (mixture of 3 lights) so that the test field (light of one
wavelength) matches the comparison field
- repeat the procedure for the test field to cover the entire visible spectrum
Quiz: Color Matching Experiment Results
Ans: - observers with normal color vision need three wavelengths of lights in
order to match all the lights in the visible spectrum
- observers with severe color vision deficiencies can match the entire visible
spectrum by using only 2 lights
