Smaller details are instead used to accentuate the beauty of the space, the Braid Box rug's subtle pattern, Trim Bedside Table's gentle curvature and the boxy contrast of the Quirk armchair, kept in the subtle Copenhagen Grey to not detract from the velvet used in the bed.
In any space, a tradeoff of louder colours and details against more subtle items is always at play. This doesn't mean items can't be unique and showstopping in their own right, their special touches can just be more in the vein of quiet luxury.
