I built this one around a blue "core" with the gold items serving to "frame" the blue. The gold is a bit darker on the gloves and boots in some light, so it looks bright on top, but dark as you go down.
The Stormwind tabard fits a bit better with its shade of gold, but the Gilneas tabard more closely matches the belt and legs. Still, there are several shades of blue going on here. Haven't found a weapon I like better than Stormrune Edge.
