The colour of skin depends on the amount and type of pigment that you have, and these are determined mostly by your DNA. The pigment in skin is called melanin, and it takes different forms giving different colours. Exposure to the sun obviously results in a tan – this is because melanin is light sensitive.
It depends what the structure of the chemical is. For example, if they are highly reactive then they are harmful because they can react with anything, like your skin. Different chemicals are harmful in different ways.
