I scrolled through hue in both modes and didn’t find a position that I could call presentable. Some are not the worst, but that’s it. I believe it can be done with 4 base colors, but this site doesn’t follow well-known color scheming principles.

While I generally agree with this particular site, it would have been nice if whoever made this put some better thought into making the light mode colors even remotely aesthetically pleasing. Supported by the other complaints in this thread it is currently completely self-defeating.

If any site I used had a dark mode with horrific color schemes like that, I'd put in place a user stylesheet or never visit again.
