I learned the importance of trichromacy when a friend and I came across a patch of wild strawberries. I&#x27;m partially red-green colorblind and for every strawberry I found, my friend found ten. They were almost invisible to me. It&#x27;s neat to see that the fourth cone&#x27;s response curve peaks right between the red and green cones&#x27; curves in tetrachromats. I bet they are amazing at finding berries.
