What's my "Origins" shade? (for make-up experts ;P*)?

If using Covergirl, I wear Natural Beige.. and with MAC Cosmetics, I do NC30... I want to try Origins Reflection Perfection (http://www.origins.com/templates/products/sp_shaded.tmpl?CATEGORY_ID=CATEGORY5723&PRODUCT_ID=PROD96#swatch).. can anyone recommend what shade would be right for me? Thanks :)
