The Truth About A Dog's Eyes

THANK YOU. THEY DON'T SEE ALL GRAY.

however, they are partially colorblind, and they see mostly gray

Red green colorblind

How is it that if the wavelengths for green are between yellow and blue, dogs can see yellow and blue but not green?

"Colorblind" is a condition associated with not being able to see a certain range of colors. Some people can't see shades of red, for an example.

They still can't cut the red wire.

OK. So. We van only see certain colors, and dogs can see colors that we can't. So if a scientist tries to show you the colors a dog sees, you might only see gray or the rainbow that we see. That might also explain why cats can see good in the dark. Not only are their eyes bigger than our when little light shines, but they see vast colors to help avoid certain objects. So your colorful paint on your wall, might look a different color to your pet.
