Photoshop colours not displaying correctly
Hi,
Using PS 21.1.3. Something's happened with my colour pallette in Photoshop, and the colours are no longer standard (with #000000 being black). Screenshot below shows that black is now a dark green colour.

I've tried editing the colour settings (Edit > Colour Settings) but none of them change it back to the standard colours. Also tried deleting all preferences (Edit > Preferences > General > Reset all prefences on exit), and also uninstalling Photoshop and reinstalling it, but nothing seems to work.
Any help would be great!
