Cats see colors differently from humans due to having only two types of cone cells in their eyes, compared to the three types humans have. Cats primarily see shades of blue and green, and likely yellow as well, but they have difficulty distinguishing reds, pinks, and warm hues, which often appear muted, gray, or confusing to them. Their color vision is similar to a person with red-green color blindness. Cats also see various shades of gray. This limited color perception is complemented by their excellent low-light vision, which helps them navigate and hunt effectively. In summary:

• Best seen colors: blues, greens, and likely some yellows.
• Poorly or not seen colors: reds, pinks, oranges, and some warm tones, which appear gray or muted.
• They do not see the full human color spectrum, more like muted or dull versions of certain colors.

This helps to understand how cats perceive their environment visually, relying more on brightness and movement than color distinctions.
