That setting works as expected in the upstream QKSMS app. I believe that the functionality is removed from /e/'s forked app, as part of /e/'s (misguided ) effort to provide a consistent UI theme across their forked apps. If I remember correctly, a similar problem used to exist in /e/'s Mail for of K-9 Mail. But I haven’t used either Mail or Message for quite a long time now, largely because of stuff like this.
For the stock Mail app I made a case when /e/ was 0.13. This case was declared as the same as another case for /e/ 0.10. Both cases are long closed which means that they are solved completely now nobody is interested to solve this.
thanks a lot for your inputs.
But I can’t understand the decision if the colors in message app have been removed due to “consistency in UI”. In that case, we could just use black & white interface everywhere even for icon of apps in Bliss, remove colored background pictures in Bliss, …
Just below an overview of what it could look like:
