### 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](./colorschemes).

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!
