As a makeup artist, I've been doing this trick for years...combining two colors to compliment each other, or to make a totally new color. Covergirl has brought this to the masses with their new product Blast Flipstick. One shade is matte, one shade is shimmer, you can mix/ match or combine. The lipstick goes on smooth and silky and lasts for hours. The best part is I only need one tube in my tiny purse when I go out at night. Very cool! *DISCLAIMER - This was not a paid testimonial, all products were furnished free of charge for this review
