There is red blue green white light what about clear
Don't confuse clear with colorless. Clear is a description of clarity; colorless describes saturation. White light is a saturation of red, blue, and green light. No light (what you would think of as darkness) lacks all wavelengths. So technically, black is colorless. But light doesn't really fall into the clear or opaque categories.
Clear Light was a psychedelic rock band that formed in Los Angeles in 1966. Just kidding. No I don't think so. Water is only clear because light passes through it. Light is all about wavelengths and energy. Red = long wavelengths, blue = short. Therefore I don't think there is such a thing as clear light (what would it's wavelength be?)
