This 'myRigCntrl.mel', creates some new controller shapes like 'Trapezium', 'Torus', 'Soccer ball', etc but the most happening feature of this script is, you can use it to assign override colors to your controllers, that too, to multiple ones. This even works for the override colors of other Object. Its very easy and simple to work with, just need to select one or more object, go for the 'Enable Override' button to enable the override color attribute of the selected object/objects, and then click on your desired color. To disable the override color option select the desired objects and click on 'Disable Override'.
