How Feline Color Vision Really Works
Cats have dichromatic vision, meaning they see primarily in shades of blue and yellow—similar to a human with red-green colorblindness. Their eyes contain two main types of color receptors (cones), whereas humans have three, which is why reds and greens appear desaturated or bluish-gray to cats. This isn't a limitation; it's an evolutionary advantage tailored to their hunting needs in low light.
- Blue wavelengths are seen vividly and clearly
- Yellow tones register as normal to bright
- Red objects appear brownish or dark gray
- Green backgrounds look yellowish or grayish
- Cats rely more on motion detection than color to locate prey
