Quartz grey vs Agreeable Gray
Quartz grey (RAL Classic) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. Quartz grey reads as grey, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. The 44-point LRV gap — 60 for Agreeable Gray vs 17 for Quartz grey — means Agreeable Gray will open up a space more effectively. A ΔE of 38.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Quartz grey vs Agreeable Gray in Real Spaces
4 real rooms side by side. Seeing Quartz grey and Agreeable Gray in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Agreeable Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Agreeable Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Quartz grey.
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. Agreeable Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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