We are used to square rose and round rose. This rose is based on square rose adding the design of radius. This gives an otherwise stiff line a soft connection.
Thus, we choose the handle models, which also use arc to neutralize stiff lines, to match such rose in great harmony.
On the finish of the suggestion, a contrast of two finishes (MBNB+ CP,SN+CP) or a single finish (Black,White,CP) is a good choice.
Details are the key to a best design!
