Optional. 

I'm of the opinion that colored text makes posts look ugly as sin and heavily out of place. Aside from that I think it's merely a crutch that people use when they fail to properly make it known who is saying what. [i]But[/i] I understand that some people think making posts colorful adds...something to them. I don't know what, but whatever, I wouldn't mind people being free to format their posts using colored text for dialogue if they want.

I'm with the Friz on this one. I've never really liked using colors to specify which character is talking.

So optional it is.
