The Right Color
Lips don't lie. The natural pigmentation of your lips is the underlying tint of every lip color you wear. That's why the same lip product can look different on you and your friends.
Most brown-based lip colors look more natural, even when the color's deep: a brownish red is easier to wear and looks softer than a bluish red.
You can get many different tones and textures out of one tube of lipstick. If you want blue-toned lipsticks to look browner (and more natural), start with a brownish lip pencil over the entire lip, then add the lipstick on top of that. These layers of color create a new shade.
If you want your lips pale, cover them with a sheer coating of foundation, then apply a light color. This is also the way to get the truest color from any lip product, as it minimizes your natural lip color.
You can also control the finish. To make a creamy or shiny lip color go matte, blot with a tissue or dust lips with powder. To add shine to a matte mouth, brush lip gloss (clear or pearly) over your lipstick.
