go to menu, multiplayer, then bottom right corner you will see create, press it, select a random name, create then do the following: (do not do this with selecting name at creating, it will fail)
size is
~ and 2 numbers like:
~54 hey hey
color is
^ and 2 numbers like:
^54 hey hey
if the ^54 or ur different numbers dissapear, write, the color or size appears when u write
and size only works for room names.
color works everywhere, including emote.
and for the full desc (replace numbers if u want):
/set desc ~54 ^41 Big Welcome
works with multiple colors like:
/sed desc ~54 ^41 Big ^91 Welcome
Btw, its suppose to be in beginner sanctuary
