What colors can't mice see?

Mice are dichromatic, meaning they have two types of color receptors and primarily see shades of blue and green. They have limited ability to perceive colors in the red spectrum, which makes red and orange appear as shades of gray or brown to them. Consequently, they cannot distinguish between these colors as humans do. Their vision is adapted more for detecting movement and contrast in low-light conditions rather than for seeing a wide range of colors.
