When it comes to selecting a perfect shade of lipstick, there are various things to consider before making a decision. The shape and size of the lip, hair color, teeth, and color of the pupil and of course the skin tone. Different shades compliment different skin tones. Thus, one must make sure the color they are choosing looks great on their complexion. A classification of shades of lipstick is given below on the basis of different skin tone:

• Fair skin tone
  While it is not to say that finding the exact cosmetic of fair skin tones is easy, it does make it a lot easier while selecting lipstick shades. However, every skin tone is divided into two undertones- cool and warm. The undertone type should also be considered while selecting a lipstick. Lipstick shades that suit fair skin tones beautifully are:
  Sweet Colours: Baby Pink, Coral Pink
  Nude Colours: Light brown, Beige
  Bold colors: Bright Red, Smoke Red
• Olive skin tone
  An olive skin tone is also known as golden skin tone. This skin tone is neutral which means they usually do not have any undertones. Nude shades look the best on olive skin tone for this very reason. Apart from that, shades of red and brown also look great on them. These shades are suggested for an olive skin tone:
  Sweet Colours: Peachy Pink, Warm Pink, Orange
  Nude Colours: Any nudes of user’s choice as all those looks wonderful on olive skin tone.
  Bold Colours: Hot Red, Smoke Red, Berry Red,
• Medium skin tone
  Wearing the right color according to the skin tone is really important. It not only makes the person look better but highlights their features. However, choosing the right lipstick shade might be a task for people with this skin tone since lipsticks with dark undertones can clash with it. Shades that look great on this skin tone are:
  Sweet Colours: Medium coral pink, hot pink
  Nude Colours: Coral nude, pink nude
  Bold colors: Cherry Red, Hot Red, Rose and mauve
• Tan skin tone:
  People with tan skin tones mistakenly assume that bright colors won’t suit them and stick to subtle, subdued lip colors. They end up getting the wrong shade of a color or foregoing lipsticks altogether. For those women guilty of this, these suggestions might help.
  Sweet Colours: Deep Coral, Coffee Brown
  Nudes Colours: Medium nude shades, Nude Pink
  Bold Colours: Hot red, Smoke Red, Hot Pink
• Dusky/Dark Skin Tone
  People with dark skin tone have limited but bold options. Their shades are mostly darker in order to compliment their dusky skin tone. Often people with dark skin tone face confusion while selecting their ideal lipstick shade. However, the plus point of dark skin tone is their undertone is mostly neutral. Thus opting for these lipstick shades might ease their confusion:
  Sweet Colours: Any contrast shades of purple
  Nudes Colours: Caramel, Chocolate-Brown
  Bold Colours: Blue-red, Smoke Red, Reddish brown
