Nocturne Blue vs Brush Blue in Real Spaces
2 real rooms side by side. Nocturne Blue and Brush Blue 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Brush Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Brush Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Nocturne Blue vs Brush Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Nocturne Blue on one side and Brush Blue 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.
