What is the best technic to adjust the colors on... I get a new LCD TV Samsung LN46A530 I've been

Question

I get a new LCD TV Samsung LN46A530 I've been able to installed and very well except for the colors. I tried to adjust the colors but either the colors are to hot (reddish) or to cold (blueish), and the greens look faded, except those showing up in the faces...

Any way, this tv have so many settings that I'm not sure where to start.

What I need to do to adjust the colors efficiently?
