Painters past and present have made a pretty strong case – complementary colours are the most visually pleasing, creating good vibrations when paired. As in life, opposites attract. Though, that’s not to say your lip colour shouldn’t mirror your bold spirit. Matchmaking lipstick shades with your skin’s natural undertone (not to mention, your hair and even your wardrobe) creates gallery-worthy levels of impact. Just the ticket when you want to stand out to be heard. In short, undertones are the basis of flattering faces – no wonder makeup artists dub the face a canvas. For instance, purple and blue-toned lipsticks best complement cool undertones. So, do you have a cool, warm or neutral undertone? Forget skin colour, simply check the veins on the inside of your wrist – blue veins means cool, green equals warm, and if you can’t tell you’re neutral.
