I recently installed OpenSUSE Leap with the XFCE desktop on an old laptop, and I quite liked the Greybird Geeko GTK themes that came with it, so I wanted to try to see if I could imitate them with QtCurve. I started with the existing Greybird KDE themes, and edited them, referencing the GTK theme in question. For a few elements I used the default Plasma OpenSUSE color-scheme, because I couldn't find something comparable to reference in gtk3-widget factory, or other reasons.
