How To Paint An Ultra-Realistic Pair of Human Lips
Step 3: Painting The Teeth
Mix a lot of water with the Parisian Blue, then paint the teeth with the wet-on-wet technique. Leave a little white for highlights, but since the lips are only slightly parted, most of the teeth should be in shadow. Drop a little Alizarin Crimson and Dioxazine Mauve in the darkest areas, as the cast shadow on the teeth (from the lips) will reflect a little of the lips’s color.
