Skin tones refer to the natural color of human skin, which can vary widely among individuals. These tones are influenced by factors such as genetics, ethnicity, and environmental exposure. Common categories include fair, medium, olive, and dark skin tones, each with its own unique undertones, such as cool, warm, or neutral. Understanding skin tones is important in various fields, including cosmetics, fashion, and dermatology. For example, makeup products like foundation are often designed to match specific skin tones, ensuring a more natural appearance. Additionally, skin tone can affect how individuals respond to sun exposure and their risk for certain skin conditions.
