Issues with colors in config

[Matars]

Using named colors does not seem to work

For example in config

header = red

I have also noticed some hex colors not working in certain entries.

It doesnt look like it checks anywhere for named colors?

Looks good, thank you.

Currently in uni exam for 8 more hours.

Will look after.

We would need to also add the new dependency for the packaging before merge, but I can do that since I need to redo the GitHub workflows.
