Alloy vs Tabby Cat Gray
Alloy (Sherwin-Williams) and Tabby Cat Gray (Valspar) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 3-point LRV gap — 28 for Tabby Cat Gray vs 25 for Alloy — means Tabby Cat Gray will open up a space more effectively. A ΔE of 2.6 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.
Alloy vs Tabby Cat Gray in Real Spaces
2 real rooms side by side. Alloy and Tabby Cat 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.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Alloy vs Tabby Cat Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Alloy on one side and Tabby Cat 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.
