+Was taken from the Oxygen Icon set (where rendering is done by inkscape).
+prerendered in green.
+
+The color was adapted on the pixel version with gimp
+by visial matching shades of blue in the other icons.
+
+Gimp tools used:
+Menu -> Color -> colorize.. :
+  with parameters approx 210, 65, 15
+Menu -> Color -> Curves:
+  Adding more billiance by dragging the ligher blue color shades more apart.
+  So from the default curve make it go a little bit steeper for 4/5 
+  of the way and then less steep.
