Przeszukiwałem pliki motywu i zmieniłem kolory wszystkich plików .svg, które były czarne. Niestety bez skutku. Później w plikach gtk.css zmieniałem dane zsapisane jako kolory w HSV. Niestety wszystko bezskutecznie. Prawdą jest, że to wszystko było zmieniane na chybił-trafił, ale i tak myślałem że uda mi się "zgadnąć" gdzie zapisana jest informacja o kolorze tła. Niestety okazało się to trudniejsze.
Czy ktoś wie gdzie taka informacja może być zapisana? Fragment z pliki gtk.css z katalogu gtk-3.20 poniżej:
