If you wish to know how to do multiple shades of any color in one letter/word
talk to fflamddwyne
I swear i got the name wrong but he is part of AxT currently in Mars 2
you can always expect to find him in M2
either with me in 420 or in some other strong alliance on that planet

but anywho
you can combine as well you know
[big][red]I like lolipops[/big][/red]
will come out a phrase that says lolipops... but big and red at the same time.
same thing for [small][blue]I like balloons[/small][/blue]
notice the dash on the second repeat-------^
you can also go [big][red]K[/big][/red][small][blue]E[/small][/blue][big][yellow]N[/big][/yellow]
to write out KEN (with a big red K, a small blue E and and big yellow N)
continue this pattern, write your whole name, copy and paste into archives and it looks awesome in chats!!!

i know
im pro

hope it helps
