If all you need to do is change the color ( and dont need to retrieve the values) then This peice of code will change the color of the graphics you have drawn in uicomp from any color to red.
var ct:ColorTransform = new ColorTransform(1,1,1,1,255,-255,-255,0); uicomp.transform.colorTransform = ct; To change from any color to green: var ct:ColorTransform = new ColorTransform(1,1,1,1,-255,255,-255,0); uicomp.transform.colorTransform = ct; Any color to blue: var ct:ColorTransform = new ColorTransform(1,1,1,1,-255,-255,255,0); uicomp.transform.colorTransform = ct; I could also provide a complete example if you want.
