I forgot to mention that red-green weak is more prevalent in males than it is in females, and it varies in severity. Across the spectrum, to a greater or lesser degree red-green weakness affects a surprisingly large percentage of American males. (And many of them don't know it. I didn't know it until the Army told me at age 22.)
