What skin tone am I and what colors should I wear?

I have pale skin and very little natural color to my cheeks. I have denim-blue eyes and medium brown hair with red undertones. I have grandparents on both sides of my family that were "ginger" - natural red heads with pale-pink skin.

When I look at the veins in my wrist (which I've been told will indicate my skin tone) they are not green or blue, but rather a teal-ish green/blue/purple sort of color. When I wear deep red, my skin really pops and has a healthy glow but my eye color takes a backseat. When I wear blue or black, my eyes pop but my skin looks sallow and ashen.

So, I'm having a really hard time finding clothing colors and make-up colors that work for me. It's nearly impossible to find the right shade of foundation (right now the closest match I've found is Ideal Flawless from Avon in Creamy Natural shade ... but it seems too pinky).

Any ideas for a sure fire way to tell what my skin tone really is? I think if I dyed my hair blonde, I'd be a warm tone OR if I put in brown contacts I could be a cool tone. It's like I'm in between the two.
