I use everyday minerals foundation in fairly light neutral, what shade of Revlon colorstay should I choose?

Everyday minerals foundation in fairly light neutral matches my skin perfectly, but i want to go over to a foundation that has a better coverage. I have already tested Revlon colorstay in sand beige, but it seems a bit too dark and yellowish on me. What should i do, is there one shade that would match my skin better or should I mix two of them? thank you for your advices :) (and sorry for my english!)
