Hi Kalpesh and Ganaraj, Thanks a lot for your reply and help.
I solved the requirement as per your suggestions. This is how I did it. var ct:ColorTransform = new ColorTransform(); ct.color = clr; //This clr value (uint) I am getting dynamically from colorpicker uicomop.transform.colorTransform = ct; //uicomop is the drawn line object whose color I am changing Thats all. Again thanks for all you help.
