Focus island with noticable countertops – too bold?

I’m trying to choose a kitchen design for an open concept living room/kitchen space (flooring would we light oak). While looking at samples, I was immediately drawn to a dark oak/striking green graphite combination. But I fear it could end up looking too dark and heavy when applied to a whole kitchen. Would having just the island in dark oak, keeping the green countertops and backsplash and having the main cabinetry in matte off-white be too disjointed/disharmonious? I can’t find example pictures of such a combination, which may be saying something…

In short, is a highlight island paired with obvious/highlight counters too much?
