Gauntlet Gray vs Porpoise
Both from Sherwin-Williams's palette. Gauntlet Gray reads as grey, while Porpoise reads as greige-grey — two distinct hue families, not close cousins. Gauntlet Gray (LRV 17) reflects noticeably more light than Porpoise (LRV 13), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Gauntlet Gray runs neutral while Porpoise is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gauntlet Gray vs Porpoise in Real Spaces
6 real rooms side by side. Gauntlet Gray and Porpoise 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Gauntlet Gray gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Gauntlet Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Gauntlet Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Gauntlet Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Gauntlet Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The brightness difference is modest but present — Gauntlet Gray gives the walls a little more lift.

5 simulated room previews — drag the slider on each to see Gauntlet Gray on one side and Porpoise 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.
