I have a xfce theme with these gtk-2.0/gtkrc theme: bg[NORMAL] = { 0.863, 0.863, 0.863 } bg[ACTIVE] = { 0.933, 0.933, 0.933 } I noticed krusader uses bg[NORMAL] for the active tab, and bg[ACTIVE] for the inactive ones
Cannot confirm. On KDE5 the tab bar uses the value "Window Background" for active tabs and a (auto generated) darker version of it for inactive tabs. Please tray again with Krusader 2.5.0. If there are still problems its probably related to Qt/GTK theme conversion. I cannot find anything in the code that the default tab colors are changed.
