      All dogs are colorblind. they only have 2 types of cones so they can differentiate blue and yellow but still would potentially struggle with stuff like light blue vs dark blue. red, orange, green aren’t visible to them at all. It’s similar to red green colorblindness in humans but not exactly. They have much stronger low light and peripheral vision though

        So they don’t see in monochrome, like in the comic? Which makes the comic weird.

        And when you call them colourblind isn’t that only by human standards? Aren’t all humans then colourblind by insect standards?

          Yes. It’s colloquial use though. Dogs are “colorblind” by comparison. But it’s not like every dog has some flaw. They see exactly as they should be.

          I’m sure some dogs are actually doggy colorblind. Like a dog that has a problem with their cones and might actually see in black and white only.

      Dogs are red-green color blind. They see a brighter and less detailed world when compared to humans. Peripheral vision is better than humans (dogs see more of the world), but distance is not judged quite as well. Dogs excel at night vision and the detection of moving objects. Figure 1 is a rough guesstimate of what a dog and human might see when viewing a color band (the electromagnetic spectrum).
