After taking some pictures for swatches, I decided to blend what I had on my hands.
Left hand is Sephora Formula X _Provocative_, with Revlon _Quick Dry Top Coat_ on the ring finger and thumb and Essie _Matte About You_ top coat on the other fingers.
Right hand is Sephora Formula X _Torque_ accented with Sephora Formula X _Provocative_. All fingers have a top coat of Revlon _Quick Dry Top Coat_.
I love how much pigment the Formula X polishes have in them! I was able to make the accent with a single, heavy coat.
