Calluna vs RAL 550-1 in Real Spaces
3 real rooms side by side. Calluna and RAL 550-1 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that RAL 550-1 will make the room feel meaningfully brighter than Calluna would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that RAL 550-1 will make the room feel meaningfully brighter than Calluna would.

Calluna vs RAL 550-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Calluna on one side and RAL 550-1 on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
