Colorschemes

ytop ships with a few colorschemes which can be set with the -c flag followed by the name of one. You can find all the colorschemes in the colorschemes folder.

To make a custom colorscheme, copy one of the default ones to ~/.config/ytop/<new-name>.json and load it with ytop -c <new-name>. Colorscheme PRs are welcome!
