S 3005-G20Y vs RAL 850-3
Where S 3005-G20Y belongs to NCS's range, RAL 850-3 is a RAL Effect color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (40 vs 38), so they'll read as similarly Medium in most lighting conditions. At ΔE 2.7, 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.
S 3005-G20Y vs RAL 850-3 in Real Spaces
2 real rooms side by side. S 3005-G20Y and RAL 850-3 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.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. 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.
