Force change colors of android apps?

Question

Android

Tell me if there is a way to change the palette of an already built android application.
It seems that here, on Habré, there was an article on how you can change the palette in an already assembled apk, respectively, by compiling a new apk. I'm having a hard time finding this article. If you provide a link, I will be grateful. UPD. Found - habrahabr.ru/post/133307/
Although, ideally, it would be nice to do the same at runtime. Tell me where to dig. Thank you.
