Gulfstream vs Pewter Green
Gulfstream and Pewter Green come from the same Sherwin-Williams collection. Hue-wise, Gulfstream belongs to the blue family and Pewter Green to the green-grey family. The 7-point LRV gap — 18 for Gulfstream vs 12 for Pewter Green — means Gulfstream will open up a space more effectively. Where Gulfstream leans cool, Pewter Green reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 30.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gulfstream vs Pewter Green in Real Spaces
4 real rooms side by side. Seeing Gulfstream and Pewter Green in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Gulfstream reads slightly lighter here — a subtle but real difference in how open the space feels.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Gulfstream has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Gulfstream reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Gulfstream has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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