How to change inline reply color for Nougat on an unrooted Galaxy 6?

[AC Question]

I recently (and mistakenly) updated to Nougat on my Galaxy Samsung 6. This user interface is awful, but my biggest concern is changing the dreadful brown color that is used in the quick reply box for my messaging app. I cannot access UI Turner, or find any other setting to change this. Themes have no effect on it either.
