I have (finally) applied usercolors. They correspond to the sphere color.

Founder: Violet (which is light purple in Wikia)

Bureaucrat: Orange

Inactive Bureaucrat: Red

Administrator: Green

Disscusion Moderator: White

Chat Moderator: Purple (which is normal purple in Wikia)

Rollback: Aqua

Blocked: Black

Banned from chat: Indigo

Globally blocked: Dim gray

VSTF: Blue

Edit 1: My glow code (a[href$=":(username)"] {color:(color) !important;} {text-shadow:0px 0px 11px (color)}) doesn't work. So I replaced those.

Edit 2: Since I added rules, I have added a new color: Red for inactive bureaucrats.
