Why are some people white and others black?
Can you tell me why some people are white and others are black?
The color of a person's skin is determined by a pigment called melanin. People with more melanin in their skin tend to have darker complexions, while those with less melanin have lighter skin. The amount of melanin a person has is influenced by genetics and environmental factors, such as exposure to sunlight.
