Question:
If the eye receives light of more than one wavelength, the colour generated in the brain is formed from the sum of the input responses on the retina. For example, if red light and green light enter the eye at the same time, the resulting colour produced in the brain is yellow, the colour halfway between red and green in the spectrum.
Surely that's the mean; wouldn't the sum be somewhere closer to the violet end of the spectrum (somewhere around blue)?

When
you merge two frequencies you don't end up with the sum of those frequencies, you end up with a modulated wave.
