Let your users choose how their documents are presented.
Thanks for Using Adobe Acrobat. If you want to change the color./Theme of the document, you can do that anyways under Acrobat -> Edit -> Preferences -> Accessibility -> Tick mark the option "Replace Document colors" and choose the colors that you wish to see on the pdfs.
Or if you are talking about Theme in Acrobat you can choose Light Theme or Dark theme as Acrobat -> View -> Display Theme -> Light or Dark Gray as per your requirement.
Let me know if you have any further concerns in This ?
