Hi Nanditha,
       Following a code snippet which should solve your problem. I am
assuming your polydata has some scalar value. The code is in JAVA.

double color = 10.0; // different scalar value
or); //cell Id is picked cell's id

Hi Jonathan,
              I still have not succeeded in my method. I am able
to change the scalar value, but the result is far from satisfying.
Can you please elborate on your approach. It will be of great
