How Grey Matter behaves on a wall
Our estimate, worked out from the hex colour, puts the light reflectance value of this Jotun shade at about 55.9; Jotun's own figure may differ. At an estimated LRV of 55.9 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 26 or over LRV 86. Its red and blue channels are within a few points of each other, so it has no undertone worth naming — it takes its cast from whatever it sits beside. 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.

The closest color to Jotun Grey Matter from each brand we carry, measured with CIEDE2000 on the manufacturers' published color values. Below 1 the difference is practically invisible; below 2 you'd only notice it with the chips side by side. Screens and printed chips aren't paint, so compare real samples before you buy. In the Muro app you can put two of them on a photo of your own wall and look at them in your light.
