You probably aren’t confused about whether your skin falls into a light or deep category, but undertones may leave you a bit puzzled. Warm undertones usually have traces of gold and red in their skin; these complexions typically get darker in the sun and never burn. Neutral undertones have an equal mix of cool and warm tones. These types typically tend to get darker in the sun and sometimes burn. Cool undertones have hints of pink and blue in their skin and may tend to burn more easily.
