It is not true that dogs are completely colorblind. While dogs do not have the same color vision as humans, they are able to tell yellow from blue. Like a human with red-green colorblindness, they are unable to tell the difference between red and green.
The reason for this limited range, in both the colorblind human and the dog, is that there are only two kinds of color receptors in the retinas of their eyes. While most humans have three kinds of color cells, with three different receptor molecules sensitive to blue, greenish-yellow, and red, dogs only have receptors for yellow and greenish-blue.
Canine eyes also lack another human trait: the fovea, an area especially dense with detail-sensing cells. As a result, their detail vision is not as good as ours. But they make up for this by having much better night vision and greater sensitivity to movement.

No dogs are not color blind. They can see colors, just not quite as we do. They see red very well.

OMG, that's something we can never be 100% sure of. We're not dogs and until dogs can talk..... its all guess work. They say most animals are color blind.

I think they can see some colors, but not the way we do. I once heard they can see a little bit of green.

Dogs have cones that can see green and blue shades, but they don't have the same rods and cones as people so it doesn't look the same. For the most part, they are colorblind.

False.
They just don't see the colors as bright as humans do.

It is a matter of opinion. I believe they aren't because my old dog was trained to pick-up different colored cups. If you said purple it would pick-up a purple cup.

Nope, they see colors, just not as many as we can and it's more blurry then ours, that's why they tend to bark at nothing at times
