You’ve probably seen these letters more often than not while searching for your best foundation match. They have everything to do with the undertone of your complexion.
Basically, they stand for “Neutral”, “Cool” and “Warm”. Women with Warm undertones usually have a golden, yellow tint to their complexion. Women with pink or red undertones are Cool. Women who have more of a beige undertone to their complexion are usually considered Neutral.
We hope this helps!
