A muted butter yellow can bring warmth to a room that receives cool, indirect light. It works best when the value is light enough to keep shadows visible.
Tune the atmosphere
Test it beside the floor and trim, then repeat the shade in a small cushion or print. Keep metals simple so the color remains the main lift.
Notice the change
The room feels sunnier because the color collaborates with the light it has, rather than pretending to have another window.
