Repost and photoshopped. Top left side of iceberg is the giveaway, the curves repeat themselves.

I think I have a different definition of 'blue'.

If you evolved on Antarctica, I wonder how this would look.

We humans evolved in environments where knowing the slight difference between green (500nm) and yellow (550nm) and orange (600nm) and red (700nm) meant the difference between finding food or not, seeing danger or not, etc. Our cone photo receptors respond to red, green, and blue to construct what we “see” in our cortices.

In the Antarctic and Arctic this would be totally different. Does a penguin need to know the difference between green and yellow? And antarctic avian neuroscientists here?
