Bo,

Once you you run the filter you should not overwrite the scalars as done on
these lines.

If you already built your colorTable for the vertices you dont need to use
the CellDataToPointData filter at all just set directly as point data.

Is your problem that colors dont appear or they are not as you intended?

Can you share how you have constructed your colorTable?  Is your code
anywhere public like github that we could look at?

Thanks
