This is pretty cool. Been playing around with "inverted colors" lately and noticed that the inversion is purely mathematical, but not perceptual. For example, if you have the RGB color (120, 30, 10) the inverse of that is (135, 225, 240). But our eyes have different sensitivity to different colors, so when you invert a whole picture, the contrast gets all messed up and it's very hard to tell things apart (wanna try it? Set your screen to inverted colors then watch a video on YouTube and you'll see what I mean). So, does anyone know how to get "perceptually equivalent" inverted colors?
