Cool colors are based on blues, greens, pinks, purples, blue-greens, magentas, and blue-based reds.
Once you have a basic understanding, you can then differentiate between for example, a “warm pink” and a “cool pink”. A warm pink is a peachy pink. A cool pink would be a purplish pink. A warm green would be a yellowish green. A cool green would be more blue.
A warm toned foundation powder is more yellow based. A cool toned one is more pink.
When you hear someone say “I am an autumn” or “I am a spring”, this means that they look best in warm tones. In contrast, “summers” and “winters” look best in cool tones. (this is based on the Color Me Beautiful method of skin typing).Looking at blushes? As a rule, any blush with a brown or peach undertone is warm. Any blush with a purple or pink undertone is cool. Some colors can work for both skintones, such as a peachy pink or a pinkish brown.
Keep in mind that computer monitors all vary in how they display colors. The best best is to try a few samples and see how they compare, or find a local MAC, Sephora or drug store where you can swatch different colors.
If you do not know your skintone, you can estimate it by referring to the following chart:
Cool: Eyes are typically blue or grey. Haircolor typically blonde, brown or black. Skin has definite blue and pinkish undertones. Cool-toned people look best in colors such as blue, red, pink and purple, or “gem-tones”. Usually look best in silver jewelry. In natural light, the color of the veins on the underside of your wrist are bluish. You can wear a white shirt and it is flattering on you.
Neutral: Eyes may be any color. Hair may be any color. Skin has unspecifiable undertones, such as pink, olive or yellow. Those with neutral coloring can wear just about any color clothing and look good. Can wear gold or silver jewelry (no preference as to which looks better)
Warm: Eyes are typically brown, green or hazel. Haircolor typically brown, black, red, auburn, blonde or strawberry blonde. Skin has yellow/orange or olive undertones. Warm-toned people look best in earthy-toned clothing, such as browns, yellows, oranges, yellowish green and ecru. Look best in gold jewelry. In natural light, the color of the veins on the underside of your wrist are greenish. You are most flattered by an off-white, cream or ecru shirt (i.e. pure white makes you look washed out)
