What you request in OP is:
"So, something like a filter that applies a CSS that inverts colors in the
document (only visually, without changing the document). Even better if it
would invert colors for the text and tables and significantly reduce the
brightness of graphical elements (like images and diagrams) until they receive
mouseover event."
Arbitrarily inverting colors would not solve the general case. In fact LO
already is capable of setting a visual theme for the document based on colors
from the OS DE theme. But for <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - Wrong automatic text color "dark grey" with black background for some GNOME themes"
href="show_bug.cgi?id=35365">bug 35365</a> [1] it was hard coded to COL_WHITE for
DOCCOLOR and COL_BLACK for FONTCOLOR--regardless of DE theme in use.
But that broke HC mode use for a11y, so in <a class="bz_bug_link
bz_status_VERIFIED bz_closed"
title="VERIFIED FIXED - Writer no longer uses Text and Background Colours from Windows High-Contrast theme for displaying document"
href="show_bug.cgi?id=71511">bug 71511</a> [2] LO now picks it up
from the Accessibility configuration for HC (even if the OS DE is not flagged
HC) and uses GetWindowColor() for DOCCOLOR and GetWindowTextColor() for
FONTCOLOR under OS DE theme control.
What is still needed is support of Dark themes for non-a11y use not bound to HC
mode of the OS DE (as noted by Bjoern in <a class="bz_bug_link
bz_status_VERIFIED bz_closed"
title="VERIFIED FIXED - Writer no longer uses Text and Background Colours from Windows High-Contrast theme for displaying document"
href="show_bug.cgi?id=71511">bug 71511</a> #11), to support dark theme
use. Those colors could be pulled from the OS DE theme, or could also have a
different fixed color assigned. It would likely require another Tools ->
Options -> View check box control.
Point is those colors would either be drawn from OS DE theme, or would be
generally fixed to support "dark" themes, but not be a simple reversal of the
COL_BLACK & COL_WHITE now used.
