Document Summary
6** metamers: different mixes of wavelengths that all appear the same color. The actual wavelength does not matter, what does is the pattern of activation across s, The green light activates the m cone by <5>, and the red light activates the l cone by. Both m and l cones are activated to a level of 15, so we can see that what matters is the relative activation. Non spectral hues= hues that can arise only from mixtures of wavelengths eg. there is no purple in the spectrum, it has to come from mixes. Subtractive color mixing when you use a paint. Eg. a yellow paint filters out certain wavelengths. When you combine yellow and blue paint, the only thing that remains is green paint. When you mix blue and red paint it gives purple. Since there is no overlap between red and blue paint, when you combine the two all wavelengths are filtered out
