I learned the importance of trichromacy when a friend and I came across a patch of wild strawberries. I'm partially red-green colorblind and for every strawberry I found, my friend found ten. They were almost invisible to me. It's neat to see that the fourth cone's response curve peaks right between the red and green cones' curves in tetrachromats. I bet they are amazing at finding berries.

This probably has nothing to do with chromacy, but is related to finding berries and other odd things. My sister is gifted with finding four leaf clovers. She walks in a field and seems to just see them. Every time she picks one, it's a four leaf. Her record find is a 7 leaf clover. I always wondered how that's possible.

  Is it possible she has synesthesia (https://en.wikipedia.org/wiki/Synesthesia https://en.wikipedia.org/wiki/Synesthesia)?

What does it mean to be partially red-green colobrlind? Isn't it the case that you either have the red-green cone or you don't?

  It's conceivable that a mutation in the gene for the red or green light-sensing protein gets a mutation that just shifts its sensitive wavelength closer to the other. So "partial" r/g colorblindness could occur if there was still some separation between those wavelengths, but not as much as is typical.

  I don't know how it works, but I have it - I can see red and green and pink in big blobs, but when there's lots of small red and green (or pink) details mixed - they seem the same to me (if their darkness is similar). Also I have problems with big uniform colour areas it there's small amount of green mixed with pink or red and vice-versa. I was making a sunset skybox for a game, and friends were wondering why the sky is slightly green - for me it was pinkish-red-yellow, but I put there some green by mistake.

    That sounds like standard red-green colorblindness.

      Good to know, I thought standard red-green color blindness is when you don't recognize these colors at all.
