I think you’re missing the point on orange. When I see aquamarine, I see blue and green at the same time. It feels like blue-green. Orange on the other hand looks and feels like a unique color, not red + green (although I know why that is). TFA is using physiology to explain why these color mixes are perceived differently.
- card_zero 2y agoYes, but at that point in the article, it's clearly talking about the amount of red, green, or blue signal being picked up by cone cells, and thus the wavelength or mix of wavelengths, which is additive mixing. It's claiming that red plus some green (in terms of stimulation of cone cells) equals dimmed red, which is factually incorrect. This part about "three filters" is overstated, I think, if based in fact at all. Presumably it's based on something the retina is known to do, but I hadn't heard before of red and green being preprocessed separately from blue, and given that we can see orange when presented with red and some green pixels, it's not exactly as stated.
