i dont think pink is fake, color is already a construct of biological human perception, why do we suddenly care if this particular brain tingle has a specific objective frequency correlated to it or not
why does the measurable frequency of light have more sanctity than the measurable biological responses in our eyes? are u telling me my short and long wavelength cones AREN'T being triggered in equal measure with comparatively little response from my middle wavelength cones? why is the biology of perception not a part of reality
it's only "fake" insofar as it's a permeable boundary drawn by language around an uncategorizable reality, but come on. it's like saying temperature is fake because "hot" and "cold" are relative terms that depend on touch
