Determine your undertone
Cool (pink, red or bluish undertones)
Warm (yellow, peachy, golden undertones)
Neutral (a mix of warm and cool undertones)
1. Check Your Veins
Push your sleeves up right now and look at the veins on the inside of your wrist. Are they blue or green? If they look more blue, you likely have cool undertones. If the veins look greenish, you’re warm. It’s worth noting, warm girls, that you’re veins aren’t actually green - they look it because you’re seeing them through yellow-toned skin (yellow + blue = green.)
2. The Old Jewelry Trick
Think about whether you look better in silver or gold jewelry (Not which you like more, but which actually makes you look more radiant, glowing, and awake.) Typically, girls with cool undertones look better in silver and platinum metals, warm-toned girls look better in gold.
3. The Neutral Test
Think about what neutral shades flatter you best. Does your skin, eyes and face look better in bright white and black hues you're probably cool-toned, or ivory, off-whites, and brown/tan shades you're probably warm.
4. Eye and Hair Color
Your eyes and natural hair color can help figure out your coloring as well. Customarily, cool people have eyes that are blue, gray, or green and have blond, brown, or black hair with blue, silver, violet and ash undertones. Conversely, warm-toned women usually have brown, amber, or hazel eyes with strawberry blond, red, brown, or black hair. Their hair tends to have gold, red, orange, or yellow undertones.
5. The Sun’s Effects
When you’re out in the sun, does your skin turn a golden-brown, or does it burn and turn pink first? If you go a nice golden-brown you’re warm-toned, while cool tones tend to burn (fair-skinned cool girls will simply burn, while medium-skinned cool-toned girls will burn then tan.)
