Problem Statement

I love using /color to distinguish sessions. I feel like the list is too short.

Proposed Solution

Extending with more would be nice, the printout of /color could print the name in their color and if someone would want to use a color not available using a #938899 or saving aliases for custom colors would be great.

Super niche, I know, but even just adding more default colors would be great. Thanks!
