38  * GtkSymbolicColor is a boxed type that represents a symbolic color.

41  * To obtain the color represented by a GtkSymbolicColor, it has to
42  * be resolved with gtk_symbolic_color_resolve(), which replaces all
43  * symbolic color references by the colors they refer to (in a given
44  * context) and evaluates mix, shade and other expressions, resulting
45  * in a #GdkRGBA value.
46  *

49  * #GtkCssProvider.
