You cannot “average” color

Of course you can. If I have two wavelengths of say 456 nm and 612 nm I absolutely can say their average [sic: mean] wavelength is 534 nm.

What is interesting is that because of the way human perception works, a human will denfinitely NOT see a 534 nm wavelength emission as being the same as the combination of two half-intensity 456 nm and 612 nm beams, since most humans are trichromatic, and our receptors have different, and most importantly, non-linear, responses.

What you mean here is averaging of the wavelengths of the light. What is done is probably is gray values of the RGB values or sth like that are averaged. Still it is not “averaging” of the color. You need to define some measurable. I can so-called average color by averaging the amount of dye for a oil on canvas version of the flags.
