Hair color is often categorized by its underlying hue, or undertone. These undertones are typically classified as warm, cool, or neutral. Shades with a bluish, violet, or greenish base fall into the cool category. For example, platinum blonde, ash brown, and jet black often exhibit cool undertones. These hues can create an icy or silvery shimmer in the hair.
Selecting a shade with a complementary undertone is essential for achieving a natural-looking and flattering result. Cool-toned shades can minimize the appearance of redness or rosacea in the complexion and can make teeth appear whiter. Historically, certain cool shades, like platinum blonde, have been associated with glamour and sophistication. Identifying one’s natural undertone can greatly influence the success and satisfaction with hair coloring.
