Add more colour options for macro buttons

Don't hide extra colours behind obscure colour combinations, instead lay them all out, add blue or even better a proper colour mixing system for macros, with the ability to recall macro colours from others.

  • I Would like for this to be implemented for Direct Selects. The problem is that all EOS desks older than the Apex don't have a physical blue LED installed. Despite that, I'd like to be able to mix Red and Green more granularly to create orange and fern green macros on the physical hardkeys. It could be that there's no brightness control on the LEDs, so I'm not sure if this is physically possible.
