Functional Gray vs Requisite Gray
Functional Gray and Requisite Gray come from the same Sherwin-Williams collection. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. The 8-point LRV gap — 45 for Requisite Gray vs 37 for Functional Gray — means Requisite Gray will open up a space more effectively. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. ΔE 5.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Functional Gray vs Requisite Gray in Real Spaces
3 real rooms side by side. Functional Gray and Requisite 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.
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. Requisite Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Requisite Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Requisite Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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