Taking all comments together the UX folks recommend to not implement this
enhancement. You probably achieve it with an extension, and please share this
with the world then. Such an extension would be a perfect example for how to
customize LibreOffice.

(In reply to Denis from comment #9)
What I suggested is pragmatic and achievable given our handling of colors drawn
from DE theme (both GUI and the on-screen document representation). 

An arbitrary "inversion" of colors for the GUI and document will never be
implemented--and we might as well close this as WONTFIX now. Sniping that this
is not what you asked for is bogus.

The general case is for something functional to work in a Dark DE suitable for
use in a low light environment without forcing the HC icon set--and picking
document and font colors appropriate to the DE.

If what is currently discussed, with picking up DE theme and auto adjusting
accessibility options is solving someone's problems, that's fine - but it has
nothing to do with my original request (the name of which was different).

There were 2 main points: inverting all colors (ALL colors, not just black and
white) and the possibility to quickly turn it on/off.

Concerning the second:

"It would be nice if LibreOffice had some kind of "night mode" that when turned
on would draw the picture of the opened documents with inverted colors"
-->
"when turned on"

"qpdfview has a hot key that inverts colors for the opened documents, maybe the
same could be implemented in LibreOffice?"

And concerning the first: the whole point is inverting ALL colors, because no
theme is going to account for all colors that can be assigned by the sender of
the document manually
(https://bugs.documentfoundation.org/show_bug.cgi?id=114147#c5).

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 bug 35365 [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 bug 71511 [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 bug 71511 #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.

You are talking about GUI. On my system LO already uses general (dark) OS DE
theme, as I have said in my opening message. I am talking about the document
colors: the document takes the most of the screen anyway and thus, the colors
in the document influence your eyes much more. What was discussed in the
previous two comments was using a custom theme for document repesentation.

LibreOffice already will pick up the colors from OS DE theme. It just has to be
forced to do so.

On Windows for example, forcing it to do so is done from the Tools -> Options
-> Accessibility panel where the "Options for High Contrast Appearance" are
located.

Select the "Use automatic font color for screen display", and "Automatically
detect high contrast mode of operating systems" checkboxes.

For now, this is not a 100% solution as our fixed "high contrast" icons is an
incomplete Galaxy/Elementary derivative only suitable for dark HC themes.

Believe tweaking this mode to allow selection of other icons sets (i.e. Sifr
Light, or Sifr Dark) but also to apply without requiring the OS DE theme signal
for HC should should provide a full DE theme driven GUI within LO _without_
changing the application colors from default "automatic" settings.
