Quartz grey vs Peppercorn
Quartz grey (RAL Classic) and Peppercorn (Sherwin-Williams) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. The 7-point LRV gap — 17 for Quartz grey vs 10 for Peppercorn — means Quartz grey will open up a space more effectively. A ΔE of NaN 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 Peppercorn in Real Spaces
4 real rooms side by side. Seeing Quartz grey and Peppercorn 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. Quartz grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Quartz 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. Quartz grey reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Quartz grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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