I love all the colors in the pans, but the ones I don't think look good on me are blues (because with my coloring I look like a Barbie) and oranges (make me look like I have some disease).
I really don't have a dislike for any color, and I like trying them all out. I tend to lean towards bright colors, and pastels, along with darker colors. I honestly like to play with different colors to see how they'll work for me.
I really think that yellowish colors are harder to pull off for some people. It can tend to wash out fair skinned people and look mucky on people with heavy yellow undertones. I find that I can wear it with a primer under neath and lot's of blending. I also like to use it as an accent color, but never by itself.
