how to create custom themes or modify existing ones

[LaraSQP]

First of all, thank you very, very much for developing Thorium and making it available to all.

Now, the built-in themes are great, but there are few and no apparent way to modify them. I could be wrong.

In particular, I need to use the 'Night' theme (visually impaired), but the font color is too bright. The other themes do not work for me.

Is there a way to modify the existing themes or, failing that, to create new ones?

Thanks again.

There is a simple way to save a preferred theme with custom formatting (font, spacing) and reuse it on different EPUB or DAISY publications, but there is no way in Thorium Reader to create a custom theme (background + font colors).

We discussed this feature internally, but the complex user interface (how to pick a background color, a font color) stopped us.

As this is not a bug in the app, but a proposed feature, I'll move it to a GitHub discussion (easier to process for the dev team). Please don't hesitate to add information about how you imagine selecting a background color and a font color.
