One common way of determining skin undertones is looking at the veins on the underside of your forearm in natural sunlight. If the veins are a blue color, then you have a cool skin tone. If the veins are green or yellow, then you have a warm skin tone. When the veins are mix of both blue and green, you might have a neutral skin tone.
Observing natural eye and hair colors can help to identify skin undertones. Typically, cool-toned people have eyes that are shades of blue, gray or green and have blond, brown or black hair. Their hair tends to have blue, silver, violet and ash undertones. Warm-toned people usually have amber, hazel, brown or black eye color, with strawberry blond, red, brown or black hair. Their hair sometimes has gold, red, orange and yellow undertones.
Many people learn their skin undertones by seeing how their face and skin looks with gold or silver jewelry placed against it. Cool-toned people look better in silver, white gold and platinum, and warm-toned people look better in yellow gold. The metal that works with your undertone color will complement your skin to make you look fresh.
Some people can determine their skin undertones by pulling their hair back and placing a white cloth, such as a towel or shirt, around their neck and shoulders. If your face looks bluish, you have a cool skin tone. If your face looks yellowish, you have a warm skin tone. Neutral skin tones typically will look greenish next to the white cloth. Many cool-toned people have pink or rosy undertones, and many warm-toned people have golden or peach undertones.
