Answer 6

That's a good question.  Color is simply a wavelength of radiation that falls within what we call the visible spectrum of light.  Any wavelength between 380 nanometers and 740 nanometers qualifies as a color as far as humans are concerned, and that means that there are millions of colors in nature, even though the human eye's ability to discern between all those colors is a different matter entirely.

There is also infrared and ultraviolet, which humans cannot perceive; dogs, cats, and many other animals can perceive colors in the IR and UV spectra to varying degrees, but we need special equipment to translate those wavelengths into colors that the human eye can perceive.

Hope this helps!

Answer 7

An unlimited number, if you consider the full spectrum of light.  It just depends how finely you want to break them down.
