    It is not caused by a wavelength.

    It is caused by a certain energy level. The wavelength is associated with that energy level. So is the frequency. Wavelength and frequency are constant. Amplitude...

    You merely assume the light has color because your brain creates the experience of color when exposed to the colorless energy.

    That is anthropocentric nonsense.

    The cells in the retina do not "see". They are not conscious. They reflexively send a neural signal centrally if a chemical reaction takes place. Color is then created centrally based on the signal...

    What does that even mean? That all EM energy has just one, fixed wavelength? Or that EM radiation can have different wavelengths, but never at the same time?
