Window grey vs RAL 810-1
Where Window grey belongs to RAL Classic's range, RAL 810-1 is a RAL Effect color. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Window grey (LRV 36) reflects noticeably more light than RAL 810-1 (LRV 33), a difference of 3 points that becomes especially apparent in rooms with limited natural light. At ΔE 1.2, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Window grey vs RAL 810-1 in Real Spaces
2 real rooms side by side. Window grey and RAL 810-1 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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.
