I don't think this is how it works.

Not exactly how it works, but close to it.

There are 2 type of melanin and we all have both but the ratio of it that give us the skin colour pigmentation. Scientist believe that human pigmentation is determine by the amount of sun/UV and diet.

Implications of correlations between skin color and genetic ancestry for biomedical research

I'd be interested in seeing how white Australians compare with say, Frenchmen. I doubt they've been there long enough for genetic changes, but it would be an interesting comparison none the less.
