Scala 12.21.18 (RAL 1037)

How Scala 12.21.18 (RAL 1037) behaves on a wall

Brillux publishes a light reflectance value of 41.1 for this shade. At LRV 41.1 this sits mid-scale — dark enough to hold its own against white trim, light enough not to close a room in. Mid-tones shift the most between daylight and lamplight, so check it at both ends of the day. For trim that reads as a clear edge rather than a smudge, aim about 30 LRV points away in either direction — under LRV 11 or over LRV 71. With 199 points between its strongest and weakest channel it holds a readable orange 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.
