Forgive my (slightly obnoxious) curiosity, but one thing I've never been able to grasp, is why a lot of people use colour for the dialogue in their posts? It doesn't serve much of a purpose so... If anyone could explain to me the idea behind it? It's only a matter of curiosity, btw, not a critique!

It's both for visual appeal and because it's a force of habit for me by now. I'm in an RP where I run a lot of characters, so the different colors help to differentiate between them.
