### Code

ColorLookupTable.java

    import vtk.vtkNativeLibrary;
    import vtk.vtkLookupTable;

    public class ColorLookupTable
    {
      // -----------------------------------------------------------------
      // Load VTK library and print which library was not properly loaded
      static
      {
        if (!vtkNativeLibrary.LoadAllNativeLibraries())
        {
          for (vtkNativeLibrary lib : vtkNativeLibrary.values())
          {
            if (!lib.IsLoaded())
            {
              System.out.println(lib.GetLibraryName() + "not loaded");
            }
          }
        }
        vtkNativeLibrary.DisableOutputWindow(null);
      }
      // ------------------------------------------------------------------

      public static void main(String args[])
      {
        vtkLookupTable lookupTable = new vtkLookupTable();
        lookupTable.SetTableRange(0.0, 10.0);
        // If you don't want to use the whole color range, you can use
        // SetValueRange, SetHueRange, and SetSaturationRange
        lookupTable.Build();

        double color[] = new double[3];
        lookupTable.GetColor(1.0, color);

        System.out.println(color[0]  + " " + color[1] + " " + color[2]);

        lookupTable.GetColor(5.0, color);

        System.out.println(color[0]  + " " + color[1] + " " + color[2]);
