Cannot perceive color with only one type of receptor. Vision is our ability to interpret electromagnetic waves. The visible spectrum is what the human eye can see. Humans are only able to see what is in the visible spectrum. There are sensors in the skin that are sensitive to uv rays, heat receptors in the skin. There are some organisms that can see in the uv or ultra red areas of the spectrum. Night goggles are used to see the heat radiated off a body, you can see where someone came from using heat bands. The wavelengths of light have to be converted using the action potential. The reason you see less color is because there are less color comparisons being made.
