Blue and orange are true opposites, which is exactly why they flatter each other so easily. This scheme takes the warmest, most lived-in version of that pairing: a deep, slightly grayed Bay Blue as the anchor and a glowing Copper Glow as the spark. Nothing here is loud or primary; both colors feel like they have spent a season near the water.
Oatmeal Linen does the quiet work in between, a soft warm cream that gives the two stronger colors room to breathe so the copper reads as a glow rather than a clash. It is the field you build everything else on.
A touch of Driftwood Slate rounds the whole thing out, bridging the cool blue and the warm copper with a gentle gray. Let the blue dominate, keep the copper to smaller accents, and lean on the neutrals to hold the calm — a grounded, contemporary take on classic contrast.
