Really? How was that measured?

..."Really? How was that measured?"

She counted them.
It took her all night.
Don't you believe her and the scientists?

I’ve done those online tests where you count the numbers of different colors you can see on the test spectrum and come up with a crazy amount.

I can also tell you what scene in nature will make a good infrared photo or not.

I also see a “glow”, for the lack of a better word, in dormant trees before they put out leaf buds in the spring weeks before they actually do.

I’ve tried to get others to see that but they don’t.

A useless talent in my own weird reality.

The general figure used is 100 detectable levels for each type of cone. Four cone types equals 100x100x100x100 colors. Normal trichromats can one million colors. A dichromat like a dog or a very colorblind person only has two types of cones so can only see about 10,000 colors.

Imagine living in a world where blue and yellow don't make green, but a completely different color.
