If you wish to color what you say (I think that it is a great way to make your post stand out), here are some color palettes to choose from. I prefer that each character has 1 color. I  will list the characters and their chosen color by their name. This is not a requirement!

To color what your character says
Use [color=] around color number character
Place number here again with no []
Close with [/color] and the word color inside.
