Amazing.
Males with colorblindness actually are color-shifted to infra-red. Not much, but enough. But I don't have to write a paper to justify a great big grant for it.
So it doesn't count.
My advice remains the same. Eat whatever is in season, and isn't too easy to catch.
In Central NW Texas, that would be italian and mexican poverty foods. Beans, corn, 'maters, onions. Cheese. Lots of cheese. And goats and squirrel.

It's a life saving feature for life in the high Arctic. Should be able to see a campfire or the glint of Sun off the back of a reindeer at 15 to 20 miles away in clear weather. Some people think of it as having superior night vision.
My relatives could literally "see through" standard camouflage used in WWII (for example).
Squirrel sounds good and I love it.
