What is blue vein undertone?

Blue vein undertone refers to the cool and blue tone that is present just beneath the surface of the skin. This undertone is typically seen in people with fair to light skin and is characterized by blue or purple veins visible on the wrist or under the eyes. Blue vein undertones are often associated with cool skin tones and are known to complement colors such as silver, white, and jewel tones. People with blue vein undertones may also be prone to redness, especially in the cheeks and nose area. When choosing makeup and clothing, it's important for those with blue vein undertones to lean towards cool shades rather than warm ones.
