Similar to the message formats, themes will exist in their own individual config files (so they can easily be swapped out or shared without touching the actual eirairc.cfg) and contain all configuration about colors in chat (and later on the look of the chat window itself). They can be applied on a server or channel-wide basis (like the bot profiles); whereas the channel will always override the server.

More things to consider for this:

• Custom fonts
• RGB colors

These are implemented as an inline-config for global, server and channel scope as of 2.8. Custom fonts and RGB colors will be another issue at a later time.
