Hey /an/, if dogs can't see the difference between green red and blue then how do they see ANYTHING on a television screen or computer monitor?

Dogs are said to have dichromatic vision -- they can see only part of the range of colors in the visual spectrum of light wavelengths. Humans have trichomatic vision, meaning that they can see the whole spectrum. Dogs probably lack the ability to see the range of colors from green to red. This means that they see in shades of yellow and blue primarily, if the theory is correct.

Bullshit. Birds, who have tetrachromatic vision see a whole lot more of the spectrum than we humans with our relatively simplistic eyes. There's even reason to believe some birds are pentachromats, which makes their colour vision more advanced than we can even imagine.
