RESPONSE:

1. So, if color is the interpretation by the brain of a wavelength of light, then where does the issue of colorblindness come in? Is it a problem due to the cones being defective, or is it a processing problem with the brain?

Color blindness results in defects in color vision, which has to do with the cones, and not processing in the brain. It occurs when one of the three cone cell color coding structures fails to function properly--one of the visual pigments may be present and functioning abnormally, OR it may be absent altogether (http://www.toledo-bend.com/colorblind/aboutCB.asp).

"Color blindness (color vision deficiency) is a condition in which certain colors cannot be distinguished, and is most commonly due to an inherited condition. Red/Green color blindness is by far the most common form, about 99%, and causes problems in distinguishing reds and greens. Another color deficiency Blue/Yellow also exists, ...

Solution Summary

If color is the interpretation by the brain of a wavelength of light, this solution examines where the issue of colorblindness comes in. It also discusses if the problem is due to the cones being defective, or a processing problem with the brain.
