I believe this may be why additive color "works". That is, if our blue-sensitive and green-sensitive cones are excited to some degree, our vision system interprets this as a color in between, even though it could be a mixture of blue light and green light. By the way, this article introduces a new term, "phenomenae," which I take to be a plural of "phenomena." However, "phenomena" is itself the plural of "phenomenon," so this must make "phenomenae" a super-plural. Wow! What a concept!! :-) (Please - no anti-spellingflame flames! I'm just kidding!)
