Many believe cats can see in color, although not exactly the way we do. In tests, cats appeared to distinguish between the low to mid light wave spectrum (higher frequency), meaning cats
responded to the colors purple, blue, green and yellow range. Red, orange and brown colors
appear to fall outside cats color range and are most likely seen as shades of gray or purple.
Cats see less saturation in colors than do humans, meaning cats do not see colors as intensely.
Blue and green appear to be the strongest colors perceived by cats.
