First of all i am not entirely sure this is possible without root but i have some hope as there exists such a solution through an app called Repainter, which uses wireless debugging to force change the colors/theme, not all features are available without root but atleast the simplest option to change colors is.
The reason i am requesting or questioning if its possible is because the app requires google play to check the license and won't go any further than the license screen on a degoogled phone, i wasn't able to find any modded version of it either.
It will be probably be very hard or impossible the app is not open source so we don't know how it changes it but just suggesting in case you decide to consider it.
