Black Swan vs Nocturnal Green
Black Swan is a Sherwin-Williams color while Nocturnal Green comes from Valspar. Hue-wise, Black Swan belongs to the grey family and Nocturnal Green to the blue-green family. With LRVs of 4 and 3, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 6.6, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Black Swan vs Nocturnal Green in Real Spaces
3 real rooms side by side. Black Swan and Nocturnal Green 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.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Black Swan vs Nocturnal Green Simulated Comparison
5 simulated room previews — drag the slider on each to see Black Swan on one side and Nocturnal 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.
