S 1002-Y vs RAL 840-1
Where S 1002-Y belongs to NCS's range, RAL 840-1 is a RAL Effect color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. RAL 840-1 (LRV 77) reflects noticeably more light than S 1002-Y (LRV 72), a difference of 5 points that becomes especially apparent in rooms with limited natural light. At ΔE 2.5, 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 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
S 1002-Y vs RAL 840-1 in Real Spaces
3 real rooms side by side. S 1002-Y and RAL 840-1 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 brightness difference is modest but present — RAL 840-1 gives the walls a little more lift.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. RAL 840-1 reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. RAL 840-1 reads slightly lighter here — a subtle but real difference in how open the space feels.

5 simulated room previews — drag the slider on each to see S 1002-Y on one side and RAL 840-1 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.
