Atlantic Shoreline vs Storm Cloud
Atlantic Shoreline is a Behr color while Storm Cloud comes from Sherwin-Williams. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 21 and 23, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Atlantic Shoreline's blue character against Storm Cloud's neutral — becomes most visible against white trim or in morning light. At ΔE 3.2, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Atlantic Shoreline vs Storm Cloud in Real Spaces
4 real rooms side by side. Atlantic Shoreline and Storm Cloud 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 temperature contrast between Storm Cloud and Atlantic Shoreline is what sets these apart most in this context.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Storm Cloud brings more warmth to the space, while Atlantic Shoreline keeps things cooler and crisper.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The temperature contrast between Storm Cloud and Atlantic Shoreline is what sets these apart most in this context.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The temperature contrast between Storm Cloud and Atlantic Shoreline is what sets these apart most in this context.

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.
