In order to change the compass indicators style we should change the control template in each of the TopIndicatorStyle, LeftIndicatorStyle, RightIndicatorStyle, BottomIndicatorStyle and CenterIndicatorStyle.
Then we should change the ButtonChromes that represent the indicators in the RootCompassStyle and CompassStyle to use the new styles from above.
Last, we should change the style for the RadDocking and set its RootCompassStyle and CompassStyle to use the modified styles from above.
I've created a sample project demonstrating how to change the left indicator for both the root compass and the regular compass. You can find it attached. Please, note that the project uses implicit styles
