Brązowy ciemny mat (RAL 8017)

How Brązowy ciemny mat (RAL 8017) behaves on a wall

Our estimate, worked out from the hex colour, puts the light reflectance value of this Dekoral shade at about 3.8; Dekoral's own figure may differ. At an estimated LRV of 3.8 this is a deep shade: it returns under an eighth of the light that reaches it, so a room painted in it leans on lamps rather than daylight. Over a pale base it usually takes an extra coat before the colour stops looking patchy. For trim that reads as a clear edge rather than a smudge, aim about 30 LRV points away — roughly LRV 34 and up. With 25 points between its strongest and weakest channel it holds a readable red 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.
