The current default Nicklist icon theme, Breeze, is barely visible when using Breeze Dark colors. A Breeze Dark compatible icon set should be created. Compatible "im-user" icons can be found in the Breeze icons-dark repo: https://github.com/KDE/breeze-icons/tree/master/icons-dark/actions. The original Breeze set might need updating as well, the current "im-user" icons look different (https://github.com/KDE/breeze-icons/tree/master/icons/actions) from what is in Konversation.
I agree. A Breeze Dark should be added to Konversation. A while ago, I remember that theme variants were created (https://forum.kde.org/viewtopic.php?t=123868&start=15) like seen in this old thread.
https://invent.kde.org/network/konversation/-/merge_requests/12 is up for review, to add a Dark Breeze theme, based on SVG (support added by same MR).
