Ladies, Do You Have Tetrachromacy? I found out about this last night on YouTube. It means you have four cones in your eyes, rather than three, and you see colors differently.

Color perception is interesting. There are genetic variations in the cones, even in people with "normal" color vision. Those with color deficiency don't even know what they are missing except that they may fail a color blind test and someone points out the deficiency to them. We can't be sure that we see things exactly as others do. Tetrachromacy is interesting. (I already knew about it from reading about it.) Those who possess it just see what they see and that's all for them.

And the story behind how our eyes turn a photon of light into an electrical impulse the brain interprets as color, shape, texture, etc. is also incredible. I used to think the photon simply hits the nerve ending in the eye and "trips" an impulse but it's much, much more complicated than that, going through a series of biochemical reactions before being interpreted by the brain. I'm color blind for grey versus green but I never noticed it until I took a test for color blindness.

I used to administer commercial drivers license exams, and at the time, there was a color blind test included. I couldn't understand that, since failing the exam didn't mean the applicant would not get the license. By the way, you probably know that the "green" traffic lights have a lot of blue in them so that people with red-green deficiency can more easily spot the green light.

As a printer for over 30 years, we would have a color blindness test every year, of course I would pass every year. What mystified the nurse is that I would pass the test for the colorblind people too.

So you're a hybrid.

Judging by the number of Black and (ugh) White photos posted on here there are many who are deficient in rods and or cones. I understand that dogs also are deficient. If dogs ever evolve to create images, their process will be called "Olfactography" Their Nude Olfactography section would be quite interesting.

Got some time on your hands? Try this color blind test. I scored 0 (no errors)

But of course, Jerry, how else would I get around?

I've wondered about some people for a while. There's a certain color called "shadow bronze" that I always say is green - nothing bronze about it. Motorola radios used to use that color.

Interesting.
