Dark Theme in Zotero altering colours in figures

vikipenef · 2026-01-22T19:17:01+00:00

Hello everyone,
I work in computer vision, so the colour accuracy of figures in papers is very important for my work. I’d like to use Zotero’s dark theme, but I’ve noticed that it actually changes the colours of embedded figures when viewing PDFs.
Is anyone aware of a plug-in, setting, or workaround that prevents this colour alteration? Any help would be greatly appreciated!

This feature in Zotero 7 can be disabled using the “View → Use Dark Mode for Content” menu option. In Zotero 8, it has been replaced with a different approach; see https://www.zotero.org/blog/zotero-8/#reader-appearance-panel-with-theme-support

Is it possible to activate the old "invert image color" mechanism in version 8.0? It seems that it has been completely removed; at least, I cannot find any way to activate it. I mostly used Zotero in dark mode and appreciated the natural color inversion in PDFs, since my documents are mostly papers with blac-drawn circuit schematics. The inversion worked very well, but now the images are not readable in dark mode; they are simply the same color as the background.

To clarify: by dark mode I mean a background color of (0,0,0) and a text color slightly darker than (200,200,200).
