Nuno:

I think your first approach is the right one, just make a sphere that is
whatever color you want and does not have any angular shading. There are
several ways to do this:

 o make a special material where the yellow color is in the "ambient"
    component and the diffuse and specular are zero.

 o similarly, make the ambient zero too, but make the material have
    a yellow emissive color.

 o make your material a "COLOR" material (as opposed to "AD") and
    it will work fine.

Also, you don't need either colors or normals for your geostate.
