London's palette gives you plenty of opportunity to change the atmosphere without changing the tile itself. White and Cream provide quieter backdrops, while Cobalt and Green have considerably more visual weight. Sage offers something softer, while Blush and Baby Pink can introduce warmth without necessarily making the room feel overtly colourful.
For stronger shades, don't feel obliged to repeat the exact colour elsewhere. A Cobalt wall can work beautifully with warm timber and brass because the contrast gives the blue more depth. Sage can sit naturally alongside warm whites and oak, while pink can be balanced with stone, cream or darker accents.
A useful trick is to look at the temperature of the colour rather than simply its name. A warm white beside a soft pink will feel very different from a cool white, even though both are technically "white."
