Suitable sunglasses color choices are most often determined by one�s skin�s �temperature�; in other words, whether one�s skin tone is warm or cool in tone.

How do you determine if you your skin is warm or cool?

In natural daylight, examine the undertone of the skin on the underside of your arm. Those with cool toned skin tend to have a pink or rosy undertone and bluish veins; while those with warm toned skin have a golden or apricot undertone and greenish veins.

In terms of sunglasses (and clothing), cool toned wearers should gravitate towards frames in blue-based hues; while warm toned wearers should look for yellow-based hues.
