Dude you are really confused. Read the question thoroughly, i will post it here- A sculptor named White, a musician named Black, a painter named Red meet in a cafe. One of them says, "My hair is black, one of yours is red, the other's is white, but none of us have the first name with own hair color." White answers, "You're right." What is the painter's hair color? Now, one of them starts the conversation saying that MY hair is black and none of us has the same first name as our hair color. So, the person saying this could be White(Sculptor) or Red(painter). But then again you see in last line that White replies to this person that he is right. Now White(Sculptor) can not be the answer as he replied to the Black haired man, who started the conversation. So the answer becomes Red(painter).
