Night blue vs RAL 590-4
Where Night blue belongs to RAL Classic's range, RAL 590-4 is a RAL Effect color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (6 vs 4), so they'll read as similarly Dark in most lighting conditions. At ΔE 1.5, 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 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Night blue vs RAL 590-4 in Real Spaces
1 real room side by side. Night blue and RAL 590-4 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.
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.

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.
