Here's a breakdown:
* Humans: We see three primary colors (red, green, blue) and have trichromatic vision.
* Most Mammals: Many mammals have dichromatic vision, meaning they see two primary colors (usually blue and green). This means they have difficulty distinguishing reds and oranges. Examples include dogs, cats, and cows.
* Primates: Some primates, including monkeys and apes, have trichromatic vision like humans.
Mammals that are known to have good color vision include:
* Primates: Most monkeys and apes, including humans, have good color vision.
* Squirrels: Squirrels have trichromatic vision, which helps them find food.
* Some rodents: While many rodents are dichromatic, some, like the golden hamster, have been shown to have trichromatic vision.
* Some aquatic mammals: Dolphins and whales are believed to have good color vision, which is useful for navigating the underwater world.
It's important to remember that:
* Our understanding of color vision in mammals is still evolving.
* Color vision varies between species and even within individuals of the same species.
* Even if a mammal is dichromatic, they can still see a range of colors, just not as many as humans.
So, while most mammals have a different color palette than humans, it's inaccurate to say they are color blind. They see colors, just in a different way!
