Describe your suggestion

Title says it all, allows the user to change the colour of the interface.

Settings

#theme and #help theme, eg. #theme GREEN, and #help theme showing a list of the colours available.

Context

Just a thought that occurred to me, thought it would be useful to add as users can change the interface to the colours they want. Unless it's left out for a reason, they can change the theme of the chat output [Baritone]

Final checklist

• I know how to properly use check boxes
• I have not used any OwO's or UwU's in this issue.

Not really useful.
