Claim: Dogs are completely colorblind

The claim that dogs are completely colorblind is mostly false. Research indicates that dogs possess dichromatic vision, allowing them to see some colors, specifically blue and yellow. Mainstream sources like Psychology Today and Britannica support this view, explaining that dogs lack the red-sensitive cone, which limits their color perception compared to humans. However, the claim is disputed by some who argue that the term 'colorblind' implies a total absence of color perception, which is misleading in this context. Thus, while dogs do not see the full spectrum of colors, they are not entirely colorblind as the claim suggests. The graders agree on direction, but vary in strength. OpenAI comes in highest (20%), while Gemini is lowest (0%). While the evidence strongly supports that dogs are not completely colorblind, some might argue that the term 'colorblind' could be interpreted in various ways. Opponents of the claim may assert that since dogs cannot perceive red and green, they should be considered colorblind. However, this does not change the fact that dogs can see and distinguish between other colors, which is a crucial aspect that the claim overlooks. Therefore, the evidence remains consistent in showing that dogs have a limited but functional color vision, leading to the conclusion that the claim is mostly false.
