Yeah, currently, the console knows how to detect TrueColor, but in this case, I just used the ANSI 256 palette rather than picking a better one when TrueColor is available...we should probably fix that!
Side note, it turns out that detecting what color palettes a terminal supports 24-bit colors is surprisingly fraught. There are a couple env variables that may be set...but not every terminal emulator will set them. And then you can use `tput`...but the terminal may not have correct data in the tput database. So that was fun to learn about!
Consider going for one of the Colorcet[0] maps if you detect you can display them. They are really useful to have a neutral view of the subject. I suggest log-scale before applying the colormap for order-of-magnitude visualization.
There's a Rust crate for these (I forgot the name).
