Olympus pens, what color setting do you use?

Like the title says, i thought it would be interesting too see what setting people are using, i have been wondered for long on what setting the "true olympus jpeg" is found?, back when i first got my first pen, i had it on i-enhance, but i soon switched to natural since i shoot allot of street photos with people, and it seems to fit my preference, but maybe i should explore the color settings more?

So what color settings do you use? do you switch often (portrait for portrait and ect) or keep it at a certain mode?
