Addition of Arc Darkest

Would be useful to include this other darker variant of Arc-Dark

Thanks for the suggestion, but this won't be implemented here.

Anything that changes the theme colors should be done in a separate fork. All current theme variants are using the same color palette and it won't be changed for single variant (or for any other reason ever).

Thanks for the reply. Does the theme colors not have a darker color than what is used in Arc-Dark that could be used to create a darker version?

It's not a matter of single darker color, but you'd need a complete darker color scheme.

Even if there was a simple way to do it, I think this is out of the scope of this project.
