The vapi presents Cogl.Color as a struct, and this is the way to
initialize structs. A workaround (completely untested, may complain
about uninitialized variable):

    Color color;
    color.set_from_4ub(...);

Looking at the documentation, it seems to me that Color should be a
class. I wonder why it is a struct.

You can try to remove is_value_type="1" from cogl-1.0.metadata and
regenerate the vapi and see if it's better. (by actually using it, not
by relying on this simple example).
