Pick a Lipstick colour apt for your skin tone. To do this, you need to know your undertone, reports femalefirst.co.uk:

Take a look at the veins on your wrists: If they appear 'blue or purple' you have cool undertones, 'green or olive' can warm undertones. If you can't really decide, then you are probably neutral.

Check jewellery that suits you: Silver jewellery is perfect for warm toned women while Gold jewellery is perfect for warm toned women. If both work for you, you are probably neutral.

A lipstick with a pink, red or blue undertone often looks better on cooler skin. A lipstick with rich yellow, peachy or golden undertones will compliment a warmer skin tone.
