How French Gray behaves on a wall
Farrow & Ball publishes a light reflectance value of 69.1 for this shade. At LRV 69.1 this is a light shade that still carries colour rather than reading as off-white. It gives back most of the light in the room, which suits north-facing walls that need the help. For trim that reads as a clear edge rather than a smudge, aim about 30 LRV points away — roughly LRV 39 and below. With 27 points between its strongest and weakest channel it holds a readable yellow cast, so it will not flatten into a neutral once it is on four walls. Order by the code, not the name, and put a test patch on the wall before you commit — a screen cannot show you how this shade behaves in your own light.
