The COAT release discussed in this reference introduces 33 shades developed with UK light in mind. That focus highlights an important part of paint selection: a color chosen elsewhere may behave differently under local daylight and the room's own orientation.

A brand's intended setting does not remove the need for testing. Compare samples through the day and under artificial light alongside neighboring finishes. Choose a shade for the actual home rather than assuming a collection label guarantees that no room will feel dark or cool.
