Need advice on paint colors.

Is your Master Bedroom and Master Bath the same color or different? Is is a coordinating color or contrasting?

Looking at painting bedroom S.W. Halcyon Green (color reads more on the blue than green side in my room). Have a long hallway leading into bathroom. What color would you paint hallway, the bedroom or bath color? Was thinking of using a contrasting color in the taupey family. Any suggestions?
