Light-skinned means that someone has a lighter color of skin. Skin color comes from something called melanin, which is a little like a coloring that our bodies make. Some people make more melanin and some people make less. The more melanin a person makes, the darker their skin will be. So, if someone has light skin, it means their body makes less melanin than someone with darker skin. But, it's important to remember that skin color doesn't change who someone is on the inside - we're all unique and special no matter what color our skin is!
