Nocturne Blue vs Rainstorm
Where Nocturne Blue belongs to Behr's range, Rainstorm is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (7 vs 5), so they'll read as similarly Dark in most lighting conditions. Nocturne Blue runs blue while Rainstorm is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 4.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Nocturne Blue vs Rainstorm in Real Spaces
3 real rooms side by side. Nocturne Blue and Rainstorm 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. 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
A front door is a focal point — small color differences read clearly at this concentrated scale. 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.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

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