Created attachment 127253 [details] Reference Screenshot SUMMARY STEPS TO REPRODUCE 1. Add a widget that supports custom icons to latte dock 2. Set latte dock Appearance tab theme -> Reverse 3. The custom icons look like this attachment. OBSERVED RESULT the icons go all white EXPECTED RESULT I expect that it would show up as normal if it can't find a dark-mode version. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE neon 5.18 KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.68.0 Qt Version: 5.14.1 ADDITIONAL INFORMATION This is the latest master branch of latte-dock built from source. I am not 100% sure whether the problem is latte-dock or the plasmoids, but I have tested 3 different plasmoids that support custom icons (custom user switcher, launchpad plasma, and application dashboard. I've also tested that it is not my icon pack having issues and tried setting it to some arbitrary icons from the Breeze icon pack, and they all have the same problem.
These are the limitations of the current plasma technology but you can blacklist if you want the applets that you don't want to be autocolored at all, You can read how at, http://psifidotos.blogspot.com/2019/02/latte-and-colors-tale.html
Thank you so much for your quick response! I didn't know what to search and my google-fu failed me. Variations of "white icon" were too generic :(. Blacklisting the coloring worked great.
