Blue Gray

No. 91

Blue Gray is a blue-green gray that reads mostly neutral, with the blue undertone becoming clearer in cool daylight. With an LRV of 69.1, it sits mid-light and can work as an all-over wall color in open-plan spaces. It tends to look grayer next to warm creams and bluer next to taupes.

For a coordinated neutral set, it pairs with Cornforth White and Ammonite, and it can sit alongside French Gray to reinforce the green-gray direction. For stronger contrast, Hague Blue and Down Pipe provide deeper blue-gray accents.
