When you say that you don't care what color the Prophet (SAWS) is, do you mean that you don't want to know or do you mean that knowing will not affect your belief in any way. Personally, I think you should want to know what your Prophet (SAWS) looked like. It's only natural to want to know as much as possible about the one you love. I truly believe that there are some Muslims whose belief might be adversely affected by their discovering that the Prophet (SAWS) was actually darker than they imagined. I think that the true description of the Prophet (SAWS) and of the Arabs of the past in general needs to be revealed in order to sift out such Muslims.
