Haha yeah, but then wouldn't it be hard to see animals. They are even more camouflaged. But i guess animals move.
Correct, grassland animals move and their camouflaged colors tend to be dull camouflaged colors
(I see yummy, yummy venison
), like you said, rather than brilliant fruity colors like shades of red. I can see dull browns and tans like in that image perfectly fine.
I've posted before (
http://www.rawpaleoforum.com/carnivorous-zero-carb-approach/does-color-blindness-suggest-a-hunter-past/) about how scientists found that color blind people can actually seeing camouflaged animals better and spotting movement better (perhaps because we are less distracted by color?) and the scientists hypothesize that color blindness developed as an adaptation that aided in spotting game animals. There was only a need for one or two spotters in each group of hunters, so it didn't become a dominating mutation (besides, if all humans became color blind then the animals humans hunt most might develop hides with colorful shades of red and green, thus canceling the benefit of color blindness), but it was an important one. In hunter-gatherer days it was a help rather than a hindrance, whereas in today's agrarian and artificial society of things like traffic lights, it has become more of the latter and is even seen as a defect instead of a special capability.
What are the details of your color blindness? What colors do you have trouble seeing etc?
Based on the color blindness tests, I have trouble seeing most of the colors other than shades of brown, yellow, blue and gray/black (if you can call that a color), especially red and green, which are the most common colorblindness colors (and make spotting motionless red apples amongst green leaves very difficult and claims that fruits are essential seem dubious).
I would be able to spot the more-yellow and black fruits you posted above. The pink and reddish ones would be tough for me. I wonder if that means that fruits with those colors might be more healthful, though that's just wild speculation and the hunting benefits of colorblindness would probably be a much larger factor behind it than any theoretical superiority of yellow and black fruits over red.
If the scientists are right about color blindness, then it is a refutation of the vegetarian/vegan nonsense about humans being natural vegetarians, not that we needed any more proof.
Here's a good quote from the earlier thread: "There are some studies which conclude that color blind individuals are better at penetrating certain color camouflages and it has been suggested that this may be the evolutionary explanation for the surprisingly high frequency of congenital red-green colour blindness."
