Frequently Asked Questions
How do we see colors?
We see colors through three types of cones in the retina, each sensitive to specific wavelengths of light. The brain combines signals from these cones to create the perception of color.
What is the role of the cones in the eye?
Cones in the retina are responsible for detecting light of different wavelengths. Each cone type is sensitive to either blue, green, or red light, and together they allow us to perceive a wide range of colors.
Can everyone see colors the same way?
No, color vision varies among individuals. Some people have color blindness, where they struggle to distinguish between certain colors, such as red and green or blue and yellow.
