This is really easy to do!!! just choose to complementary colors like purple and gold, red and black, pink and purple, red and white, white and black etc!! choose the lipstick colour first (harder to get every color in a lipstick) apply lipstic all over lips as you normally do then choose your second colour in a pigment form!! apply using a small brush or your finger to the inside of the lip top and bottom! and there you have it two tone lips!!!!
