SUMMARY
in some books (for example functional programming in java [ ipfs cid: QmQ72DfkfaZ3iuqdapUxf4HZ798HoDHSCdoiqkr2voDhTh ] pictures in the attachmments) the colors in dark mode dont have enough contrast. 
on some other books it works perfectly. my wild guess is that if the epub defines a font color, the dark mode changes the background, but not the font color. 

STEPS TO REPRODUCE
1. install arianna flatpak
2. open the same book on light mode and on dark mode 
3. try to read 

OBSERVED RESULT
dark gray font on dark gray background
with inverted colors in the settings light gray font on wihte background

EXPECTED RESULT
same contrast as in light mode (white or light gray font)

I can confirm that I have the same problem with several books (it doesn't occur with others)

I can also confirm this issue. I have seen it in a few ebooks.
