Deep Space vs RAL 810-5
Deep Space is a Benjamin Moore color while RAL 810-5 comes from RAL Effect. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 11 and 10, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.9, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Deep Space vs RAL 810-5 in Real Spaces
1 real room side by side. Deep Space and RAL 810-5 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Deep Space vs RAL 810-5 Simulated Comparison
5 simulated room previews — drag the slider on each to see Deep Space on one side and RAL 810-5 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.
