There is an irony here that people are not happy with their natural skin colour, and it's no "pigment of the imagination"
Melanocytes are the cells which produce melanin pigment as a natural skin protection factor. The most important risk factor for malignant melanoma, the most lethal form of skin cancer, is UV (ultraviolet) light. Yet its frequency has grown faster than any other cancer, especially but not only in light-skinned / fair-skinned people. Don't forget the sunblock creams, lotions and sprays, the only ones that really matter!
