Yes, each cell in our body has a nuclei, and in each nuclei there are all the bodies chromosomes including eye color.
There are more genes than chromosomes in skin cells.
No. the skin cells wouldn't be capable of producing other skin cells. No nuclei are found in the cells of the outermost layer of your skin. A company claims that its moisturizer can restore and rejuvenate these cells.
skin color is influenced by many genes so several different gene pools can produce the same skin color
There are cells within the bottom layer of the epidermis (the stratum basale or stratum germinativum) called melanocytes. Melanocytes secrete a pigment called melanin which is responsible for giving our skin its color. Their main function though is to shield the nuclei of the keratinocytes (the main cells of the epidermis) to protect them from ultraviolet radiation from the sun. That's why we appear to tan in the sun.

because they haven't got the right genes
Genes, or genetic material, are basically instructions encoded in DNA for building cells in an organism. Genes code for many different traits like blood type, hair color, and skin color. Scientists frequently debate the role of genetics in behavioral traits, the nature vs. nurture argument. Currently it is unknown to what extent genes code for things like violence or altruism.
epistasis
Why wouldn't they? The skin cells on the soles of your feet are just like the skin cells everywhere else on your body - the skin on the soles of your feet would look identical to skin anywhere else if not for the fact you walked on them, which hardens the flesh. But, yes, they have nuclei.
Melanin
melanin
Skin color is the pigmentation of your skin based on the amount of melatonin in the cells. Less melatonin means lighter skin color; more is darker.
