Yes. They are red-green colour-blind.
Dogs do not see colour anywhere near the same as humans. They were once thought to be dichromats--essentially severely colour blind. Modern research now suggests that dogs do see SOME colour, but not to the extent that humans do. So there is absolutely no reason, or evidence, that dogs would cower at anything based on it's colour.
Essentially all of them. The idea that dogs are colourblind is a major misconception. However, their colour vision is less developed than humans. Dogs are dichromats, meaning their eyes possess two types of cone cells (colour receptors). Humans are trichromats, meaning that our eyes possess three types of cone cells. Dogs indeed can see colour. However, the spectrum of colour they can see differs from how we see it. When we see the rainbow, we can see the colours red, orange, yellow, green, blue, indigo and violet. A study by Jay Neitz at the University of California Santa Barbara demonstrated that dogs see the world in yellow, blue and grey, with varying shades.

Dogs are NOT colour blind, they see things that are black,white,blue or yellow better than any other colour. They see most colours,some of them might be pale though.They can see well in the dark too :) Hope this helps
Dogs and cats actually do see colour but green, yellow, and orange look similar to them. Bright orange and red look dark or brown. Purple and blue are easier for them to tell apart from other colous.
After research I believe its blue
No type of dogs can see in colour, I don't know why though.
Most mammals are believed to see blue color, including dogs and cats. Additionally, some birds, such as owls and hawks, are thought to have limited color vision and may perceive blue.
Dogs can see black and white. Even if you see something colorful, it will always be black and white to dogs. That is a lie. They can see various shades of blue. Dogs can see light blue to dark blue, but the rest is black and white. I've heard they can see yellow too. (In various shades)
dogs can see just as well if not better as we can exept they dont see colour.
It is thought that all dogs can see in limited colour. It is a common misconception that dogs see only in black and white. Research has found that dogs have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs have only 2 types of cones so they do not experience the same spectrum of colour vision that we do. It is thought that dogs can see blues and yellows the best and that they are able to differentiate between various shades of blue and violet, but that they have difficulty distinguishing reds from green. They are considered similar to red-green colour-blind humans.
Yes they can. You're confusing them being unable to see with them being just a little too stupid to react. Dogs can also see in colour (almost). They can tell black from white and blue from yellow but not red from green.
Dogs DO see in colour, abeit to a lesser extent to a human's colour vision. It is a common misconception that dogs see only in black and white. Research has found that dogs have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of colour vision that we do.
