Description paulystefan 2019-04-01 17:04:16 UTC
important enhancement for kids and teens against short sightedness.


dark theme  with black background against short sightedness, eye strain and better sleeping after late work

see science results in german:

and in english:

So in all software products with white background, a dark mode with dark theme against short sightedness and eye strain should be available in first step.

in android 10 a dark mode will be available. 
in iOS 11+ intelligent color invert without photo invert is available.

Also significant reduction of energy consumption in smartphones, tablets and laptops with OLED display with black background.

in actual LO 6.2 themes from Firefox are not available, so dark theme of Firefox are not available.

working mode with inverted colors for white background and normal black types 
is not available.

in Android 10 dark mode is coming. 
in iOS 11+ intelligent color invert is available. 

So libre office viewer should have dark mode.

windows 10 goes with dark theme first steps into dark mode.

LibreOffice aims to comply with the system theme (=> see also). So if you run your Android with a dark theme it should work also for this app. Please submit screenshots to illustrate the issue.

All your links are off-topic, sorry. If you run into trouble with LibreOffice Viewer please make a screenshot of the particular issue. Talking about the desktop version there are options to change the colors. And again, supporting the system theme / mode is what we aim for not a special solution with a button or the like to switch from a to b.

german pdf print of geo article against short sightedness

for german developers see german geo article or this pdf.

Night modus for working and reading is necessary with modified icons and tables in all versions of libreoffice not only the viewer also in macos, linux and windows.

Bug 118320 for Windows and bug 118017 for Mac are confirmed, I guess we can do the same for this one...
