As another commenter has noted, the most likely reason for that is missing gamma correction. An sRGB value of 128 is dithered as 50% black, 50% white, when it should be around 78% black, 22% white.
- makeworld 6y agoNo, the article and the library does gamma correction, and I've observed the exact effect you're talking about before. I'm not sure why the images are appearing too bright for the person above. Maybe because it's using pure colours like red and green which are bright on RGB displays? I should've chosen a different palette.
- codeflo 6y agoThat’s what I get for parroting claims I haven’t verified! That’s great, thanks for the correction. Hmm, as far as I understand the math, your palette being pure colors shouldn’t really matter if the display calibration were perfect. Which I guess is an unrealistic expectation. :)
- MayeulC 6y agoOf course, my monitor isn't calibrated ^^" However, pure red will always appear brighter than non-pure red, even at the same luminance (~energy), which is what Helmholtz-Kohlrausch is about. IIRC pure red appears brighter than other pure colors as well at the same luminance level, but I am not sure how computer monitors interact will all of the above...
