Whether your teeth appear yellowish or white depends on the color of your lipstick. The best trick for white teeth is easier than you think: cool, blue tones neutralize the yellow tinge of the teeth and make them appear whiter. The shade of blue neutralizes and makes teeth look brighter, since blue is the complementary color to yellow. In addition, bluish lipstick reduces optically unattractive discolouration. Suitable shades for whiter teeth are mauve, fuchsia, violet, berry, lavender, pink and dark red.
You should definitely avoid lipstick colors with a yellow tinge, such as coral or copper, if you tend to have yellowish discolored teeth. A little tip: These shades are more suitable for making a fresh holiday tan look more intense.
More complicated than you think: When buying lipstick, it is best to seek advice from a competent specialist cosmetics shop. There's no harm in testing the new lipstick tone in advance. It is simply best to see directly on the lips whether the color harmonises with the teeth and complexion. In addition, it can help if you find out more about your personal color type and take advantage of a color consultation in order to be on the safe side when buying cosmetics.
