VTK Glyphs

I am working with carotid.vtk file and I added cutter, contour and glyphs - my glyphs have good direction and everything but they are colored the same (they are all blue) even though their size is different, im using scalars as a color array and in paraview it works perfectly fine (vectors are colored from blue to red), I really have no clue why it doesnt in VTK.
