This can be a tough question so we break tones into three distinct categories: cool, warm and neutral.

A pale, rosy, ebony, or dark-red cast to skin usually indicates that you have a cool tone.

Warm, yellow, golden, and honey tones usually lend themselves to a warm tone. 

If you have a blend of both, or are more olive toned, then you have a neutral tone to your skin.

We have found a easy way to determine your skin tone, pull the hair back from your face and drape a white cloth (pure white not ivory) around the neckline so white is the only color next to the face. The white cloth reflects the true tone color of the skin. Colors from clothing cast shadows on the face that sometimes make it hard to determine skintone. From here you will be able to look at the face and determine the underlying color. Once you have determined the skin tone it will be easier to find a foundation color.
