Can we please stop changing the bio to say the chemicals dyed his hair green and magically put permanent lipstick on him?
The chemicals bleached his hair and skin white. We know this because they bleach Harley's hair and skin. After jumping in the chemicals we can see the green run from his hair and patches become lighter. We can see the lipstick smudged in some scenes. His makeup and eye shadow isn't on in the Arkham flashback scenes, making his eyes look flesh-ier and unhealthy.
I know we don't have an official source saying 'This is fact', but we can infer based on the movie. Nowhere in the movie is it infered that the hair and lips were a result of the chemicals, that's like assuming the grill and tattoos are a result of the chemicals.
we have two characters who have taken acid baths. We get to see one character do it. Both have white skin afterwards and one has bleached hair as well. It is safe to assume that, upon falling in the same vat, Joker had the same reaction (albeit he seems whiter and therefore must have been submerged longer).
Some good points made, but what you're arguing is still every bit as dubious as what you're arguing against. The finer details of such things were not revealed in depth, so we will never know for sure.
Yeah i get that, just saying that logically it would make sense that he dyed his hair and used lipstick. It just feels like a bit of a goof to give the chemicals credit for that in the context of the film.
