Nocturne Blue vs Obsidian Green in Real Spaces
4 real rooms side by side. Seeing Nocturne Blue and Obsidian Green in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Nocturne Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom

Front Door

5 simulated room previews — drag the slider on each to see Nocturne Blue on one side and Obsidian Green 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.
