Step 1: Pick the darkest color, usually plums and browns or even dark red, and apply to lips. In my case, I chose Benefit's Ms Behavin lipcolor. It's the left swatch in the picture.
Step 2: Apply a red or pink tone on top of the first color. In my case, I chose Lancome's Red and Sensual Lava lipstick. It's the middle swatch in the picture.
Step 3: Apply a light pink, cream, or orange color as the final layer. In my case, I chose Estee Lauder's Pinkberry. It's the right most swatch in the picture.
So what do these three lipsticks come together to look like? See the picture below! Good luck with your attempt; remember it may take a few trys before the perfect trio of lip colors will come together to create a summer lip color for you!
