-- Kool aid works on any animal fiber. Dying colored fibers is called overdying, and will produce different end results, and they ain't always what you expect. For example yellow over blue doesn't always yield green.
Many colors that we see, for example blues in feathers, aren't the result of pigment in the fiber, but how the physical structure of the fiber refracts the light. Pigments absorb light, and reflect back to our eyes the light they don't absorb. The structure of a fiber will bend the light, and send a particular frequency of light back to our eyes. This makes a difference in dying, because of the effect I noted in the first paragraph. There are many books, many websites, and large e-lists devoted to dying. Throughout history, it's been one of the most important economic items in manufacturing. Astonishing stuff really.
