Colour That Survives A Grey Morning

A colour chosen under showroom lighting is a different colour in a north-facing room in November. Test it where it has to live.

Paint A Metre Square

Not the little card. A metre square on the wall the colour is actually going on, with two coats, left for two days and looked at in the morning, at lunchtime and with the lamps on. Half the colours we shortlist are rejected at that stage and none of them is missed.

Watch The Undertone

A green with a grey undertone reads calm beside natural timber and cold beside a warm white ceiling. The undertone, not the hue, is what makes two colours you liked separately look wrong together.
