  • What is color blindness?

  • A color festival.

  • No.

  • Color blindness or color deficiency is a vision problem.

  • Now, our eyes have light sensitive cells called rods and cones.

  • Can I put ice cream on these cones?

  • Rods are responsible for black and white vision.

  • They do not detect color.

  • Whereas, cones detect color.

  • There are three types of cones.

  • One cone perceives red light, another perceives green and the third perceives blue.

  • Together, these cones help us to see the whole spectrum of colors.

  • Now in some cases, when one or more types of cones do not work properly, it causes color blindness.

  • People with such deficiency have difficulty in distinguishing between certain colors or shades.

  • For example, in red green color blindness, the apple tree may appear like this.
