Hmm, I would say: I guess so ;-)

You have to call your LUT _and_ then define it.
Look at the VTK file formats documentation page 8.

This should do the trick:
# vtk DataFile Version 2.0
Molecule points
ASCII
DATASET POLYDATA
POINTS 2 float
0.0 0.0 -1.29308565
0.0 0.0 1.29308565

LINES 2 6
2 0 1
2 1 0

POINT_DATA 2
SCALARS radius float
LOOKUP_TABLE colors
1.66 1.66

LOOKUP_TABLE colors 2
1.0 1.0 0.0 1.0
1.0 1.0 0.0 1.0

HTH.
