Yeah, I'm thinking there's some related genetics here rather than the color of food being more likely to turn someone off with regular vision. I think both things can be true though. I'm red-green colorblind, and you're exactly right, it's not that I can't see red or green, they are just a bit harder for me to discern. I know grass is green and blood is red. I know a cardinal is red and a tree is green, however, it's harder for me to find the cardinal in the tree, which is how we learned I was colorblind as a kid. I doubt food looks different enough to me that it would turn normal sighted people off but I'd be ok with it. I'd bet there's some gene related to colorblindness and sense of taste or smell or something.
