Would be helpful to see what other hardware/cabinets look like

I always tell my clients if they are changing one/two things up, then keep something else consistent. For example if you want to change the style of the hardware, then keep the finish the same as the other hardware in the room. Or if you want to change the finish of the island hardware then use the same style. This way the space looks planned and polished instead of it looking like a mistake or that you couldn't find matching hardware. Especially since you already have different colored cabinets. It is a good way to add interest without going too far with it.
