Calling all makeup artists/experts!

I need help :( I have been religiously searching for a foundation shade to match my skin tone. My face is pretty pale compared to my body because I exfoliate and whatnot. The shade I'm wearing here is Loreals infallible pro matte foundation in 102 she'll beige. I thought it had a neutral yellow undertone which is what I THINK I need, but it looks pinky. Inside during the day, it looks okay on my skin, but outside in sunlight, and with flash, I look horrendous. What gives?? I've tried many other brands and colors. I'm light, so I tend to go for colors in the beginning of the spectrum, but I have a golden tone too... But towards the end or even middle of the spectrum, those tend to be too dark! Sigh :( I'm tired of this but I hate my skin without makeup. Help a girl out?
