Hey folks!  I'm becoming fascinated by in-game text colours and OOC text colour within gameplay threads.  Is there any recognized standard of colour choice? Is there a colloquial colour usage?

i.e. each character's spoken text is represented by a different colour (i chose red for my fighter/warrior/angry-dude type character in a game recently)
or
i.e. a player's underlying mood is represented by colour (cool, calm - blue / angry - red etc)

and what about
i.e. OOC text within gameplay threads as always orange?

thoughts? trends? tendencies? how is colour used on rpol? could it be used more effectively?

also while i'm at it - do folks tend to post in-game using past-tense or present-tense? I find this interesting too, and discordant when a game's players write in different tenses.

apologies in advance - I have a slight linguistics background and so I'm geeking out on this a bit.

:)

Most games I've been in use Orange for OOC chat within an in-character thread and standard black text for the OOC thread.

Character speech colors is usually either "Pick whatever you want," or "I hate it and as the GM I am banning it from my game."  I've never really seen any variety outside of that.

I hate colored text; I disabled it.

I post in the past tense.
