OpenGL doesn't change colour depending upong glPolygonMode so the OSG's osg::PolygonMode can't do anything different either. If you want different colours then you'll need to use a seperate osg::Material (maps to glMaterial) to create a different colour, or change the osg::Geometry's colour or textures. Please have a look at OpenGL documentation for details of how glMaterial (osg::Material) and glColor/glColorArray (osg::Geometry) work together.
