Hi Jeff,

Isn't that what this function is for:
http://www.vtk.org/doc/nightly/html/classvtkGraphLayoutView.html#a45b37f2ed2ee24681616deea31b98e00

?

I did what you said (using a vtkViewTheme) and it still seems to have
the problem of 2 vertices get colored one color (red) and two another
(green).

The new version is here:

Thanks,

David
