People with vitiligo can do anything. There is no limitation.
Because of the sensitivity to the sun, I believe that people who work in occupations that imply a large exposure, should take an extra care.
Once I met a tour guide who has vitiligo universal, and works very exposed to the sun, but has put me that was never a condition of crippling, always using protectors which inhibit the action of the sun.
I don't see any work that can't be played because of the vitiligo.
