ELI5: Skin colour relating to sunburn susceptability.

If darker colours absorb heat/light and lighter reflects, why is it harder for darker skinned people to get sunburn? 
Wouldn't absorbing the energy from the sun make you burn more?
Has it got something to do with uv being outside of visible light spectrum?

The darkness of your skin comes from a pigment called melanin. The darker your skin, the more melanin in it.

Melanin absorbs UV radiation, it's the thing the damages cells which leads to sunburn or in worst cases to cancers/tumors.

Think of the dark pigmentation in your skin as an umbrella against rain. The umbrella gets wet, but it protects you underneath it. Melanin gets hit by radiation, so that the vulnerable stuff beneath it doesn't.

Do note, even people with a lot of melanin will burn in the sun eventually. It's resistance, but not absolute protection. An umbrella won't save you from a typhoon.
