It would be nice if you had some examples.

Acerola recently made a video about how Silk Song has banding with dark colors due to poor dithering (and how to fix it): https://www.youtube.com/watch?v=au9pce-xg5s https://www.youtube.com/watch?v=au9pce-xg5s Highly recommend for any graphics programmer that might think dithering is unnecessary or simply a "aesthetic choice".

  To lend more credibility, the devs added more dithering in the next patch.

A great many can be found here: https://en.wikipedia.org/wiki/Dither https://en.wikipedia.org/wiki/Dither (also a very nice explanation of why dithering is a fundamental signal processing step applicable to many fields, not just an "aesthetic".)

  Interesting!

The average desktop computer is running with 8 bit color depth the vast majority of the time, so find or generate basically any wide basic gradient and you'll see it.
- doormatt 1y ago
  I think you mean 24 bit. 8 bit would only be 256 colors total.
  - recursive 1y ago
    8 bits for each of R G and B. So a grey-scale gradient indeed has only 256 colors available. Any gradient also will have about that many at most.

      In most gradients, the transitions in R, G, and B are at different places.
      - recursive 1y ago
        True. Also, in most gradients, the full range of R G and B is not used. In rgb(50, 60, 70) to rgb(150, 130, 120), there are only 200 total transitions.

        In terms of color spaces, SRGB (the typical baseline default RGB of desktop computing) is quite naive and inefficient. Pretty much its only upsides are its conceptual and mathematical simplicity. There are much more efficient color spaces which use dynamic non-linear curves and are based on how the rods and cones in human eyes sense color. The current hotness for wide color gamuts and High Dynamic Range is ICTCP (https://en.wikipedia.org/wiki/ICtCp https://en.wikipedia.org/wiki/ICtCp) which is conceptually similar to (https://en.wikipedia.org/wiki/LMS_color_space https://en.wikipedia.org/wiki/LMS_color_space).

A very simple black-to-white gradient can only be, at most, 256 pixels wide before it starts banding on the majority of computers that use SDR displays. HDR only gives you a couple extra bits where each bit doubles how wide the gradient can be before it starts running out of unique color values. If the two color endpoints of the gradient are closer together, you get banding sooner. Dithering completely solves gradient banding.
