Question 1
Who proposed the trichromatic theory of color vision?
◦ Young and Helmholtz
◦ Hubel and Wiesel
◦ Hering
◦ De Valois
Question 2
Why is it difficult to see colors in the dark?
◦ Cones, which help us to see color, don't work well in dimly-lit conditions.
◦ The darkness provides complementary wavelengths, which effectively erases the color from the objects.
◦ Rods, which help us to see color, are only utilized in brightly-lit conditions.
◦ Darkness inhibits rods and cones from the process of transduction and therefore prevents the perception of colors.
