If you have access to the GtkStyle object, you might as well use the
GdkColor arrays in the struct directly. For example,
style->base[GTK_STATE_SELECTED] will give you the background colour for
selected text in an entry widget.

Symbolic colour schemes are a relatively new addition to GTK+, so I
would avoid using them directly. It is much safer to use the bg/fg and
base/text arrays to get colour information from the theme.
