Question

What is color constancy, and what are its limitations?

Short answer

We can’t see the true color of the object due to color constancy.

Step-by-step solution

Definition of color constancy.

Colour constancy is the ability of our brain to produce the same color when illuminated by different light, ignoring its true color. For example, a green apple looks green in white daylight. But when viewing during the sunset, in the red light, the color should look different. But our brain still processes it as green. This is the color constancy.

Limitations of color constancy.

Sometimes due to color constancy, we can't see the true color of the object, the brain just predicts the color of the object based on experience and environment.
