Humans can see several thousand shades of color but have cone photoreceptors that are sensitive to only three (perhaps four) wav
elengths of light. What is the best explanation for why we see so many colors? Select one:
a.Color perception is dependent on the millions of rods as well as cone photoreceptors.
b.Color perception is achieved by activation of various combinations between the three cone types.
c.Shades of color are purely psychological and learned by association with age, infants only seeing in black and white. Incorrect
d. Colors are added and enhanced in the primary visual cortex of the brain.
B. Color perception is achieved by activation of various combinations between the tree cone types.
Explanation:
Human eye have only three photo receptor ( three wavelength) but they can see several thousands of shades of color because color perception is gained by combination of these three wave length cone types ( RED, BLUE AND GREEN) into various combinations. Our retina have two types of cell:- cone cells and cylindrical cells. Cone cells are responsible for the identification of color.
