I'd avoid the blue/red coloring which connotes party affiliation in American politics.

I actually have been struggling with this for sometime. Not specifically the political colors, but just in general: dealing with (or not) colors with coded meanings.

On numerous occasions I've come across circumstance where I've been tempted to use red and green. Red is, of course, bad while green is good. Right?

Trouble is, I feel like that kind of editorializes the data and unless there is a very clear definition on what is good and what is bad, I'm not totally comfortable with using it.

This gets even crazier when people get hyped up on their 'stop light' concept, and want red/green/orange, whereas wtf does orange actually mean?

Is it better just to use non-meaning driven colors in general?

@dan l: A far simpler reason not to use red/green combinations is that people with colour blindness cannot tell the difference.

Also, this has application to people with normal vision... I recall a study where users where shown two colour swatches one red and one not, and asked to click on the red one (which could be either side). Their response times were measured, and then plotted against the hue.
What came out is that people spent a longer time with green then they did with other colours (except those shades very close to red). So, the human brain finds red/green a harder combination to differentiate than red/blue or even red/pink.

Different cultures also have different color meanings. Be aware of the audience...
