Warm, cool, or both? Which set of colors do you think I would look best in?

I have a orangeish-yellow (mostly yellow) skin tone. When I wear makeup, I use Bareminerals. I'm a golden-tan in their make up line. My undertone is ever so slightly pink/white in places. Lately my skin and hair have been losing its pigment. Not really sure why though. I'm getting of topic, sorry about that. I want to wear eyeshadow but I don't know which set of colors to go for.
