What color curtains go with a grey sofa?
Grey sofas work with many curtain colors, but the right choice depends on the tone of the grey and what the rest of the room is doing. The clearest way to choose is to see curtain options on your actual window wall with your sofa in the room.
Cool greys pair naturally with blues, soft whites, and silver tones. A pale steel-blue curtain next to a cool grey sofa keeps the room cohesive and calm. Warm whites and off-whites read softer and warmer, which can counterbalance a cold grey without introducing a competing color.
Warm greys, which have beige or taupe undertones, open up to a broader palette. Earthy greens, terracotta, and ochre all work well and add color to a room that might otherwise feel muted. Deep navy or charcoal curtains next to a warm grey sofa create a moody, high-contrast look that works well in formal or evening-use rooms.
