Coastal Blue vs Blustery Sky
Coastal Blue (Jotun) and Blustery Sky (Sherwin-Williams) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 19 vs 22 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. ΔE 3.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Coastal Blue vs Blustery Sky in Real Spaces
2 real rooms side by side. Coastal Blue and Blustery Sky 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. The distinction reads clearly at room scale, making the choice between them concrete.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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