I'm always really pleased with Itch's visual design, especially dark mode - it's nice to be able to bring up pages in a dark room and not be blasted in the face with a blaring white background and garish colors (unless someone's themed their game page like that).
But the theming on analytics is really difficult to read once you have more than one game. There's not much of a distinction between the colors assigned to each game, they can appear to blend together when the bars are ordered light to dark, and it seems like the colors assigned to each game change depending on what's currently active in the panel. I can't really tell at a glance which game is doing well without clicking (or hovering, which I can't do on mobile) - I just know it's the sort of purplish one that's darker than the brighter magenta one.
It'd be nice if we could just assign hex codes to each game when viewed in the dashboard, so we could use our own palettes.
