After shortening the wavelength of light, you produce a quantitative change which means colour of light changes from red to orange, through yellow, green, blue, indigo ending in violet. That's a change in quality. I'm sure you view colour as being subjective and based on human perceptions, same as with this theory you stated before in this very thread.
As a matter of fact wave length of light is objective, that is, can be measured objectively taking x-rays. Due to the (quantity) wave length, x-rays can penetrate the body. Not all light can do this. The change in what the light itself can actually do, is determined by the length (measurement of a quantity) of the wave.
