Description Wyatt Gosling 2013-07-18 20:20:33 UTC

If you view an .epub document with a dark colorscheme active (eg Obsidian Coast), you frequently end up with text that is very hard (eg light grey text on a white background). My guess is that it pulls fallback colors from the user's colorscheme.

While it is likely the epubs fault for not specifying the color of every asset, most epubs do this, so it is probably something Okular should handle. Okular should use fallback colors that will work with the assumptions of most epub makers (dark text on a light background) even if that clashes with the user's desktop theme.

Reproducible: Always

Steps to Reproduce:
1. Switch the color scheme to Obsidian coast
2. Open an epub in Okular
Actual Results:  
light text on a light background (usually)

Expected Results:  
Dark text on a light background
