Lazarus Dark theme...

[madel]

On my Linux pc, either qt5 or gtk2 dark mode make Lazarus practically unusable, properties values in object inspector are in unreadable, dark blue color.

You can always customise all of these through Tools > Options > Form Editor, Object inspector etc...

Anyone know how to change colors for the dropdown autocomplete window?

Edit: Figured it out, from the expected options window under Editor > Display > Colors, you have to change the Foreground of each property under Object pascal. My mistake was that I set Default text amd Reserved word  etc. and all code looked correct but not in autocomplete window.

What could make it easier is using Delphi IDE Theme Editor and apply a color scheme then edit the things you need.
