RAL 5003 Sapphire Blue

With an LRV of about 4, RAL 5003 Sapphire Blue absorbs most of the light that reaches it. It makes a wall recede and a room feel smaller, and it needs good light to show its color. RAL does not publish an LRV for it, so this one is calculated from the color. RAL is a physical standard. #263855 is a screen approximation of RAL 5003; sources list slightly different HEX values, so check a RAL card before ordering paint.
