…with colors in the cpulines styles, not sure if you would like to do something like this, but in my mind the important thing is uniqueness of the CPU cores, so there aren't 2 CPU cores with the same color, cause then its really hard to see the graph, but not sure this is the best way to do it, just a suggestion :)
I agree it can be hard to differential the cpu lines when there's a lot of cpus. I think this feature might be good as its own colorscheme actually. Otherwise it would probably break a bunch of custom colorschemes.
