Question

What is color constancy, and what are its limitations?

a) Color constancy is the ability to see colors consistently; it has no limitations.

b) Color constancy is the ability to perceive colors independent of lighting; it has limitations under certain conditions.

c) Color constancy is the ability to distinguish between colors accurately; it has limitations under all conditions.

d) Color constancy is the inability to perceive colors consistently.

Answer 1

Color constancy is the ability to perceive consistent colors under varying lighting conditions. It has limitations under certain conditions.

Step-by-step explanation:

Color constancy is the ability of the eye-brain system to discern the true color of an object illuminated by various light sources. It allows us to perceive consistent colors even when the lighting conditions change. This ability is explained by the retinex theory of color vision, which postulates the existence of three retinexes or image systems associated with the three types of cones in our eyes.

However, color constancy has limitations under certain conditions. For example, it may be affected by extreme lighting conditions or when the colors of the surrounding objects are similar to the object being observed. It also relies on assumptions about the lighting environment, such as the assumption that the light source is white.
