Replying to Deaf people "hearing" their own thoughts

Me and a bunch of my friends were talking about this~if people were born deaf could they 'hear' themselves think~I wouldnt think so since they dont know what sound is?? And what color to blind people see since they cant see anything else? it could be black but since they dont know what color is they couldnt tell u so it could be like black or white or even like red??
