We're neutral on this. In some circumstances, colors can be beneficial. In others, it is not. Thats the plain truth of it. 

Saying someone is better/worse for (not) using colors is just sad. Its what they say that matters, not how much, or how little, color there is on it. When we're composing collabs with people, we almost consistently use different colors for each person, though when the collab is posted, the colors are typically discarded in transit.

What we consider far more relevant than the question of "to use colors or not" is this: "If colors are to be used, which colors?"

[color=#ff0000][b]a bright red[/b][/color] might sear the eyes of people more than a [color=#888888][b]a medium gray[/b][/color] would, but they both differ greatly from the guild's default white.

Some of the discussion above feels a lot like various people are shouting "You're wrong because you don't agree with me!" at each other from different hilltops.
