hi,
By using your approach, I could add only three conditions whereas
my drop down has 7 values in it and I want one color scheme for each
drop down value.

Say the choices as

1) Open -- to be displayed in "Red" color
2) Re-Open -- in "Orange" color
3) Fixed -- in "Blue" color
4) Work-In-Progress -- in "Light Blue" Color
5) Closed -- in "Green" Color
6) Hold -- in "Teal" color
7) Unable-To-Test -- in "Cyan" color

Shall wait for your valuable inputs/suggestions in the above
regards.
thanks,
Swarna Kumar T.S
