Question

why no pink color light?

Answer 1

pink light cannot be made from photons of a single wavelength ,

Answer 2

This has nothing to do with "photons of a single wavelength" (btw: a photon always has a single wavelength). - it only has to do with how color-vision in the human brain works and beyond that it's a philosophical question more than anything else...

Watch this[1] praveenr5883, or just read about color-vision on wikipedia...
