@eeeps@front-end.social Great blog post! I learned a ton. One question. You wrote:

Isn't it rather that our eyes have non-uniform perception of the same number of photons at different wavelengths? Or am I missing something?

@trs@metasocial.com Of all the statements I make that's one of the ones I'm shakiest on – so I might have things wrong. But I think we're on the same page; if we're 8x more sensitive (or whatever) to that green than that blue, and they have the same apparent lightness, that means there is 8x more light being emitted by the blue swatch. I think. https://en.m.wikipedia.org/wiki/Luminous_efficiency_function
