How do I change the color scheme of individual documents?

I’m using LibreOffice 7.3.7.2 on Pop Os.

I like the look of LibreOffice Dark mode color scheme, but this applies globally to all LibreOffice documents. I generally use dark mode whenever I am working on personal projects but for document (i.e., slides, letters, resumes) that I intend to share I use the default color scheme. The problem is that when I switch to default '‘light’ mode, all my documents are now light and vice versa. I would like to have my color scheme be consistent.

How would I create a color scheme that applies only to individual documents, and is it possible to create a template, so I can create a new document with the same color scheme?

You do know that a document created on a computer with a dark mode or scheme will appear the same as the same document created on a computer with a light mode or scheme? When you share a document the recipient won’t know what scheme you were using when you made it.

In other words it is the appearance on the user’s screen that has changed colour, not the document.

Why are you switching themes? The appearance on screen won’t be consistent if you do that.

Or maybe I don’t understand the question?
