In natural light, check the appearance of your veins beneath your skin. If your veins appear blue or purple, you have a cool skin tone. If your veins look green or a greenish blue, you have a warm skin tone. If you can't tell whether or not your veins are green or blue, you probably have a neutral skin tone.
White Cloth Test: Put a white cloth next to your bare face and observe what cast your skin takes on. Skin with warm undertones will appear yellowish, while skin with cool undertones will seem blueish or pinkish.
Grab a pure white piece of clothing or even just a piece of white paper. In bright, natural light, hold the item up to your face. If your skin looks pink or rosy by comparison, you're cool toned. If your face looks more yellow, your undertone is warm.
The best colors for cool skin tones are on the cool end of the color spectrum. The top colors to wear include emeralds, deep purples, lavender, pink, ice blue and bright blues. If you want to incorporate a warmer color into your outfit, you can use extremely pale yellows, rose reds and rubies.

Hold up a white paper in the mirror.
In a place with bright, natural light, hold up a piece of printer paper and look at how your skin reacts to it. If your skin looks pinkish against the paper, you probably have cooler undertones; if your skin looks yellow against the paper, you're probably a warm tone.
Sun Exposure Test: Observe how your skin reacts to sun exposure. If your skin burns easily and doesn't tan, you have a fair skin tone. If your skin burns as well as tans a little, you have a light tone. If your skin tans easily but rarely burns, you have a medium tone.
Look at your wrist veins under natural light.
If your veins appear to be green, you probably have warm undertones. If they're blue or purple, you probably have cool undertones. If they are a mix of both, you may have neutral undertones.
Hair Colours for Cool Skin Tone
Icy blondes and ash-based browns tend to complement cooler skin undertones, but if you are very fair then you might find that a platinum blonde hair or a very dark smoky brunette hair will wash you out.
People with warm undertones look great wearing foundation with orange and gold hues. If you have cool undertones, then your skin has more blue or pink in it. In this case, you'll want to look for a foundation that has more of a bluer-base in shades of red and pink. Neutral undertones have a mix of both.
I wanted to test skin color separately to find out whether it's important to perceptions of beauty. I found that without regard to physical features, people prefer light brown skin over dark brown skin or pale skin,” said Frisby, associate professor of strategic communication at the School.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people.
The most frequent skin color coded was white with pink undertones, which comprised 42.3% of the anatomical images.
If you've picked the wrong undertone:
If you are COOL and pick a WARM or NEUTRAL foundation, it will look yellow on you. If you are WARM and pick a COOL foundation, it will make your skin look pale and icy. If you pick a NEUTRAL foundation, it will look grey.
Consider how sun affects your skin
“If you have blue/purple veins and burn easily, you likely have a cool undertone. If your veins are more aqua/blue-green color and after time in the sun you burn first and then tan, you are likely a neutral undertone.”
A beige skin tone will fall somewhere between a dark skin tone and a pale skin tone, but there are a wide range of tones it may present as, so it's important to take the time to determine exactly what your tone might be.
Neutral skin tones fall somewhere in the middle of the skin tone shade charts. It's rare for extremely fair-skinned or dark-skinned individuals to be true neutrals. Usually, your skin tone is closer to beige, buff, or “medium.”
Blue or purple wrist veins typically indicate that you have cool undertones, while green or olive equates to warm, and blue-green veins suggest that neutral undertones are in effect. Cool = Veins on the underside of your wrist appear blue/purple. Warm = Veins on the underside of your wrist appear green.
Although the color gray is commonly associated with cooler, cloudy days, there are both “cool grays” and “warm grays.” Cool grays have more blue undertones, while warm grays are grounded in yellow and brown — similar to “greige,” a combination of gray and beige.
The undertones of beige neutrals may be yellow, pink, orange/peach, or green. You may sometimes notice more than one of these undertones, but if it's truly a beige, you won't see any other colors emerge beyond these. Beiges are considered warm neutrals and are best paired with brown or black roofs, NOT gray ones.
Pick a color, any color. Trace your finger over that line to its direct opposite and you have two complementary colors, one warm and one cool. If they complement on the wheel, they'll look complementary in your wardrobe.
