RAL 630-3 vs RAL 630-4
Both from RAL Effect's palette. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (7 vs 6), so they'll read as similarly Dark in most lighting conditions. At ΔE 2.9, 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.
RAL 630-3 vs RAL 630-4 in Real Spaces
3 real rooms side by side. RAL 630-3 and RAL 630-4 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.
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.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

RAL 630-3 vs RAL 630-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 630-3 on one side and RAL 630-4 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.
