How F1.04.56 behaves on a wall
Dulux publishes a light reflectance value of 59.9 for this shade. At LRV 59.9 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 in either direction — under LRV 30 or over LRV 90. Its red channel runs ahead of its blue, so it reads warm and will sit comfortably next to timber, brass and terracotta. 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.
