Boney,
I looked your camera up on dpreview.com.
From the review/spec sheet, I can't tell if you can manipulate contrast or saturation (I suspect not).
HOWEVER
You do have some interesting settings. In the "shooting" mode you have portrait and landscape. I suspect this is just a depth-of-field preference, but it may adjust the parameters in question as well.
Under "My Colors" you have a "vivid" setting. This should certainly boost your saturation. this combined with -1/3EV should produce a noticeable difference. Maybe give it a try.
Thanks for the link. I'll be there for a while.
