GTK+ extends the CSS syntax for images and also uses it for specifying icons.

+ 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.
