[vtkusers] Graph vertex coloring not working

[David Doria]

I am trying to make a simple tree and color the vertices:

http://www.vtk.org/Wiki/VTK/Examples/Graphs/ColorVertices

I am expecting a red, green, blue, and yellow vertex, but instead I am
seeing two red and two blue vertices.

Can anyone what I am doing wrong?

Thanks,

David
