+      Symbolic icons from the icon theme are recolored according to the
+      -gtk-icon-palette property. The recoloring is sometimes needed for images
+      that are not part of an icon theme, and the -gtk-recolor syntax makes
+      this available. -gtk-recolor requires a url as first argument. The
+      remaining arguments specify the color palette to use. If the palette
+      is not explicitly specified, the current value of the -gtk-icon-palette
+      property is used.
