Style guide for text colour usage?

[Lokean]

Another day, another incidental class design query.

Are there any guidelines on colour usage is log messages/talent descriptions/effects? Obviously, if I make a new damage type I should just assign it a colour I think is thematic, but what about messages to the log? Stealth warnings come up in #LIGHT_RED# and stuff to do with traps is #CADET_BLUE#. Is there a general rule for some colours, or do I just go with whatever I like the look of?

Can I get away with colourising text in a talent description? Could I make a 'flavour' section at the top of the talent description in italics and then a basic mechanical description below, or is that too much of a departure from the norm?

Obviously, I can try and determine heuristics from pulling code apart, but a style guide would be pretty useful.

Well, concerning the coloured text in talent descriptions, I do that for my addons.
Usually if a class has a certain mechanic that comes up often, like Ruineds Lightning Rod, or to further highlight the really important stuff - like existing bugs. (for example, Stoneshaper had two big bugs for a long time, namely not letting you walk through summoned walls and the no-air-needed talent sot stopping suffocation.)

There isn't really a style guide. Put as much or as little effort into the descriptions as you like.

The only question is 'will the people that use my mod benefit from this', and if the answer is yes, your formatting might get stolen for canon stuff.
