These results provide strong evidence that cats are dichromatic with a neutral point near 505 nm. This neutral point is nearly identical to the neutral point of the human deuteuranope, making feline vision a more accurate a model for red-green colorblind individuals than normal
What is vision like for a cat?
A cat's vision is similar to a human who is color blind. They can see shades of blue and green, but reds and pinks can be confusing. These may appear more green, while purple can look like another shade of blue. Cats also don't see the same richness of hues and saturation of colors that we can.
What do cats see when they look at humans?
When cats look at humans, they see another large cat lacking balance and agility. With limited cones and many rods, cats are colorblind (may not see you well in bright lights), near-sighted (see a blurry figure when you're 20+ feet away), and struggle to identify their human's faces 50% of the time.
