Olive skin can have either warm or cool undertones, or a combination of both. If you have an olive undertone, its usually a mistake to go for a warm (yellow) foundation. Instead, look for one with a slight golden color. When it comes to hair color, warm olive skin tones have yellow or green undertones that can clash with certain hair colors. The best hair colors for warm olive skin tones are shades of golden brown paired with a medium olive skin tone, which create a natural, beachy look. Cool undertones will see blue or purple colored veins, while warm undertones, as well as neutral tones, will see greenish veins, or have trouble seeing a distinct color.
In summary, olive skin can have warm or cool undertones, or a combination of both, and the best foundation and hair color choices depend on the undertones of the skin.
