I recently read that they see a pastel-like color spectrum. Regardless of what colors they do and don't see, they obviously have fantastic vision. Cats, both wild and domestic, are the best hunters on land.
Animals which see in the dark better use more rods than cones. Rods are...defining or something and cones are colours and stuff. I cant remember hey its physics I did a speech on it last year. Cats have a [And other hunters probably] thing called a taptum lucidum [I cant remember the word but its something like that]. It acts like a mirror for the light, rebounds in the eye heaps. Okay thats off topic. But thats how they see so well in the dark and I hear cats notice movement [Thanks to the rods] more than colour but perhaps they have enough cones to see colour.
