Colour Story
Why Calypso blue endures
Calypso blue occupies a rare point in the colour spectrum — precise enough to feel intentional, versatile enough to shift completely with the light throughout the day.
At LRV 42.7, Calypso blue sits in the mid-range — substantial without being dark, ideal for larger walls.
The NCS formula S 4040-B20G captures this precisely — and our trade partners can mix it to order at a fraction of the original price.
Insider Secret
The same NCS. Different names.
The formula S 4040-B20G exists across multiple premium brands under completely different names. The colour is identical. The price is not.
