Quick answer
The biggest mistake with page color and contrast is using an extreme value because it looks good for a moment. Test readability over a real page instead.
Low contrast can look soft but become tiring to read.
Mistake 1: changing too much at once
Change one setting, read, and compare. If you change four settings together, you cannot tell which one caused the problem.
Mistake 2: copying another person’s setup
Different screens and different eyes need different settings.
Use examples only as a starting point.
Mistake 3: judging from a preview
A clean settings preview is not the same as a dense chapter, table, footnote, or long paragraph.
Always test on real material.
Fix
Reset to a normal preset, then add back only the changes you can explain.
If one change clearly helps, keep it and leave the rest alone.
Detailed troubleshooting checklist
Work through the problem in this order: first check page color and contrast itself, then the app, then Android or the device. Keeping that order prevents you from changing many things when only one part is wrong.

What to remember
The answer does not need to be complicated. The useful result is that you can avoid settings that make reading harder even when they look attractive at first without repeating the same setup every time.
