Skin color is determined by the amount of melanin present in the skin, not keratin, hemoglobin, or collagen. Melanin is a pigment responsible for giving skin its color and is present in varying amounts depending on an individual's genetic makeup. Keratin is a structural protein found in skin and other tissues, but it does not affect skin color. Hemoglobin is responsible for carrying oxygen in the blood, and collagen is a protein that helps maintain skin structure, but neither have a direct impact on skin color.
