Are Cats Color Blind?

By The Detect Color Blindness editorial team Last reviewed 2026-07-05

Cats aren't colour blind in the "black-and-white" sense, but their colour vision is limited and muted. Their eyes are tuned for detecting movement in dim light rather than for rich colour.

What colours can cats see?

Cats have far fewer colour-sensitive cones than humans and are effectively dichromat-like. Research suggests they see:

Blues and yellows reasonably well, though less saturated than we do.
Reds and greens poorly, these tend to look greyish or washed out.
Colours overall as muted and pale compared with human vision.

Where cats excel is low light. Their eyes are packed with rod cells and a reflective layer (the tapetum lucidum) that boosts night vision, and they detect motion extremely well, trade-offs that come at the cost of fine colour and, to some extent, sharp detail.

Cats vs dogs

Both are red-green limited, but cats' colour vision is generally even more muted than dogs'. Both are built for hunting at dawn and dusk, when detecting a small, fast movement matters far more than telling red from green. Compare with how dogs see colour.

Choosing toys your cat can see

Like dogs, cats respond best to blue and yellow toys, and, above all, to movement. A toy that darts and flicks will grab a cat's attention far more than one that just sits there, whatever its colour.
