Do people have different color perception?

Our colour vision starts with the sensors in the back of the eye that turn light information into electrical signals in the brain – neuroscientists call them photoreceptors. We have a number of different kinds of these, and most people have three different photoreceptors for coloured light.

Why do you see spots when you close your eyes?

Closed-eye hallucinations are related to a scientific process called phosphenes. These occur as a result of the constant activity between neurons in the brain and your vision. Even when your eyes are closed, you can experience phosphenes. At rest, your retina still continues to produce these electrical charges.

What is the significance of the experiment involving colorblind monkeys?

An experiment involving colorblind monkeys may have some significance. Maureen and Jay Neitz, through using gene therapy and surgery, were able to make colorblind monkeys react to color as if they have always been able to see it. You can view the results in the video below posted by USA Today.
