Umm, the pattern of light is a constant. It is made up of both waves and particles which do not vary. In addition, color does not react to light – color is merely a perceptual concept used to describe in uniform, standard nomenclature which wavelengths of light are reflected off an object.
Of course it is a constant. That is why you never need to adjust ISO, Shutter or Aperture. Anyway, I was talking about basic patterns or “direction” of light (i.e. Rembrandt, Butterfly, Short etc. I am sure you’ve heard it before)
Now about color. Try hitting a red apple with green light and see what comes of it.
