RAL 820-1 vs Agreeable Gray
RAL 820-1 (RAL Effect) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. RAL 820-1 reads as blue-grey, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. The 3-point LRV gap — 60 for Agreeable Gray vs 57 for RAL 820-1 — means Agreeable Gray will open up a space more effectively. ΔE 7.3 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 820-1 vs Agreeable Gray in Real Spaces
5 real rooms side by side. RAL 820-1 and Agreeable 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. Agreeable 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. Agreeable Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Agreeable Gray 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. Agreeable 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. Agreeable Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

RAL 820-1 vs Agreeable Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 820-1 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.
