Blustery Sky vs Whirlpool
Both from Sherwin-Williams's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Whirlpool (LRV 29) reflects noticeably more light than Blustery Sky (LRV 22), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 6.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blustery Sky vs Whirlpool in Real Spaces
2 real rooms side by side. Blustery Sky and Whirlpool 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.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Whirlpool reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Whirlpool reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
