Wheels and roof need to match in my opinion but the roof colour really affects how you see the body colour. In your climate this isn't too much of a problem but for us who live under dark skies these colours particularly need the white to lift them.
I ultimately chose BRG for it's classic look and it's worn well, not showing the inevitable swirls or marks that dark colours can.
