How to Choose Art by Color Without Matching the Sofa
Colour can connect an artwork to a room without turning the artwork into an accessory.

Find the dominant field
Look first at the largest area of colour in the artwork. A red background behaves differently from a print with one small red accent. The dominant field is what the room will notice from a distance.
Use repetition sparingly
One repeated colour elsewhere in the room can be enough. A book spine, lamp, textile or small object can create the connection. Matching every colour usually makes the room feel staged.
Contrast is also a strategy
A yellow work on a grey wall or a black-and-white work in a colourful room can create a stronger result than close matching. If the room is visually quiet, the art can be the part that refuses to be quiet.
Check the wall colour in daylight
Warm and cool wall paints change how the print is perceived. View the wall in both daylight and artificial light before choosing a frame and final position.
Use filters as a starting point
A colour filter is useful for reducing hundreds of works to a manageable set. After that, choose on image and subject. Colour can get you to the right shelf; it should not be the only reason to buy.
