The rank cards system currently allows you to modify the background color and text/highlight color. In the future, modifying other aspects of your rank card may become possible. Rank cards show your user or server profile, as well as your display name or nickname if you have one, username, rank, level, and XP progress toward next level. The colors set with the /settings command on a per-user basis take priority over the server colors set with /config. The color option can be a hex code (#a564ee) or named color (blue).
More customizability will likely be added to rank cards in the future.
