Gray Flannel vs Pewter Green
Gray Flannel (PPG) and Pewter Green (Sherwin-Williams) come from different manufacturers. Gray Flannel reads as grey, while Pewter Green reads as green-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 10 vs 12 — so neither will read significantly brighter or darker than the other. A ΔE of 10.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gray Flannel vs Pewter Green in Real Spaces
10 real rooms side by side. Seeing Gray Flannel 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. 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.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Patio
Exterior colors look different in open light — both tend to read lighter outside than on an interior swatch, and shadows read more strongly. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. The distinction reads clearly at room scale, making the choice between them concrete.

Gray Flannel vs Pewter Green Simulated Comparison
5 simulated room previews — drag the slider on each to see Gray Flannel 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.
