Gulfstream vs Thermal Spring
Gulfstream and Thermal Spring come from the same Sherwin-Williams collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 3-point LRV gap — 21 for Thermal Spring vs 18 for Gulfstream — means Thermal Spring will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 11.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

5 simulated room previews — drag the slider on each to see Gulfstream on one side and Thermal Spring 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.
