The tab widget's active tab background color is something that can be played with in code--and already is, in fact. With the default Breeze color scheme, observe how it has a subtly lightened background color compared to the rest of the view background. Since everybody loves @manualjlin's mockups, faithfully implementing those always seems like a good idea to me. :) REPOSITORY R31 Breeze REVISION DETAIL https://phabricator.kde.org/D29264 To: abstractdevelop, #vdg, #breeze Cc: manueljlin, filipf, ngraham, cblack, plasma-devel, dmenig, Orage, LeGast00n, The-Feren-OS-Dev, konkinartem, ian, jguidon, Ghost6, jraleigh, zachus, fbampaloukas, squeakypancakes, alexde, IohannesPetros, GB_2, trickyricky26, ragreen, crozbo, ndavis, ZrenBot, firef, skadinna, himcesjf, lesliezhai, ali-mohamed, jensreuterberg, aaronhoneycutt, abetts, sebas, apol, ahiemstra, mbohlender, mart
