Warm undertones refer to the subtle hues in a person's skin that give it a golden, peachy, or yellow tint. These undertones can affect how colors look on an individual, influencing choices in clothing, makeup, and hair color. People with warm undertones often find that earthy colors, like olive green and warm reds, complement their skin best. To determine if you have warm undertones, you can look at the veins on your wrist. If they appear more green than blue, it's likely you have warm undertones. Additionally, gold jewelry typically enhances the appearance of warm undertones better than silver.
