Warm undertones refer to the subtle hues in a person's skin that lean towards yellow, peach, or golden shades. These undertones can influence how certain colors look on an individual, making them appear more vibrant or washed out. People with warm undertones often find that earthy colors, like olive green and warm reds, complement their complexion 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, while silver may not be as flattering.
