Cobalt blue vs Pearl night blue
Cobalt blue and Pearl night blue come from the same RAL Classic collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Their light reflectance values are nearly the same — 6 vs 8 — so neither will read significantly brighter or darker than the other. A ΔE of 1.8 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cobalt blue vs Pearl night blue in Real Spaces
2 real rooms side by side. Cobalt blue and Pearl night blue 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.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

5 simulated room previews — drag the slider on each to see Cobalt blue on one side and Pearl night blue 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.
