                                Yellow dyes are more than just a bright color; they are a complex science, with some synthetic types, like Tartrazine (FD&C Yellow No. 5), being produced from petroleum-derived compounds. The specific chemicals present depend entirely on whether the dye is synthetic or derived from a natural source.
