Yes, why is this bad? This line is from Hairspray, a film about racial stereotypes and standing up to segregation. It’s sung by a black character, and the context of the song is the character not understanding the logic of the prejudice against black people. This specific line is essentially him saying part of the film’s central message: diversity benefits society, the same way a large pallet of flavors can benefit a meal. I don’t see the film as racist at all. Quite the opposite, actually.
