People will be able to change the skin colour

Alvin Toffler : writer, scriptwriter
As people will discover more about genetic make-up, they could change skin colour to any pigment desired. The feasibility of the process needs altering certain genetic code in order to get the job done. People will be probably walking around with cyan blue and purple skin. If people will take the luxury of skin-color modification far, a new definition of beauty would emerge because of it.
