pink, pooches and pondering

For most of us, Valentine's Day is Over. If there is residue for you, here's hoping it's the sweet kind. That said, let me share with you:

There is no pink, at least in the world of light.
This brief animation explains:

What colors don't we see? Could radio waves, gamma rays, x-rays and cosmic rays be pink ? Possibly. I expect they are not totally though. I fantasize that there is more to the rainbow.

It's well known that dogs are color blind. They see images in shades of black, gray and white. I wonder how their species would be different if they could see a peacock in full color. And their food (blegh). And how would humans, as a species in whole, be different without color?

 

What does color mean to you?

 

And, what will our existence be like when we see beyond our current visible luminous rays?
