Serious Gray vs Steely Gray
Both from Sherwin-Williams's palette. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Steely Gray (LRV 30) reflects noticeably more light than Serious Gray (LRV 23), a difference of 8 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Serious Gray vs Steely Gray in Real Spaces
1 real room side by side. Serious Gray and Steely Gray 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.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Steely Gray 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.
