Cones=color
...because they both start with C.
Rods detect light. My cones are defective.
"Color deficient" is the politically correct term.

Oh, right.
It looks like a hand to me.

Re: Cones=color
So can you detect any colour or is it all black&white?

Wikipedia, to the rescue!
I took a psychology course entitled "Sensation & Perception", which finally made me realize that I actually am color deficient and not just wearing a label some quack felt like handing down. There was a picture in the textbook of an image that someone with a color deficiency would not be able to discern. And sure enough, I couldn't see the image.
I can never see the picture in those Magic Eye 3-D posters, either, although that may be something else entirely.

Wikipedia's article on color vision deficiency has the image I was talking about. It would seem that I am deuteranopic, as I see no number there at all. The numbers in the other examples are faint but still legible. I can barely see that there are numbers in the protonopic example, but it's hard to tell if it's a 3 or a 5 and a 7 or a 2.
