What Are We Looking At?
Imagine your eyes are like a box of crayons. Humans have three main colors: red, green, and blue. When we mix them, we see all the pretty rainbow colors.
But animals have different boxes! Dogs only have two crayons. They can tell if something is yellow or blue but might think purple looks gray. Bees are like artists with four crayons because they add ultraviolet light. This helps them find flowers that shine in invisible UV patterns.
Why Do They Need It?
Animals need to see colors differently based on what they eat and who hunts them. Birds use their extra color vision to pick ripe berries and spot mates. Fish living in deep water use special lenses to see the faint light above them.
So, when you look at your pet, remember that they are seeing a secret world of colors right under our noses!
