It looked like pale brown or almost lavender in the movie at times. But it never looked elephant grey on the screen.
This is a blue coat/brown coat thing all over again. Do you want it screen accurate OR prop accurate?
The three original renders should ALL be scraped. None fit the character... especially not that weird happy Harley Quinn smiley one.
Personally, I don't like the new one either. Mouth shape looks wrong; upper lip should be a lot fuller.
