Edit colors directly in `config.toml`

[insipx]

This is something else I would love to be able to do. Tracking https://github.com/Keats/tera and https://github.com/Keats/gutenberg.

I think the best way to accomplish this would be through Tera templating in SCSS. Another possibility is extending Gutenbergs Tera instance. Like #1 , however, it requires more research.
