Geometry nodes can be whatever you desire :)  

It all depends on what data you put into your geometry and what kind of material it is using. If you want to have multiple colors in the same geometry, you can for instance use GL_TRIANGLE and QSGGeometry::defaultAttributes_ColoredPoint2D() and a QSGVertexColorMaterial.
