Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. The 3-point LRV gap — 23 for Concrete grey vs 20 for Attitude Gray — means Concrete grey will open up a space more effectively. A ΔE of 1.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Concrete grey vs Attitude Gray in Real Spaces
2 real rooms side by side. Concrete grey and Attitude 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.
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. Concrete grey 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. Concrete grey reads slightly lighter here — a subtle but real difference in how open the space feels.

Concrete grey vs Attitude Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Concrete grey on one side and Attitude Gray 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.
