Yes. It was all the time.

The

void load_colour_scheme ( float col[][4], float r, float g, float b, float
a ) ;

routine does nothing but filling the colour table specified with the
calculated values.


Hence, it can be and is used by both

puSetDefaultColourScheme

which modifies PUI's _global_ colour table specifying the default colours
that are used when a widget is created and

puObject::setColourScheme

which modifies the widget's _local_ (!) colour table.
