Nile Blue vs S 5010-R90B
Nile Blue (Benjamin Moore) and S 5010-R90B (NCS) come from different manufacturers. Hue-wise, Nile Blue belongs to the blue family and S 5010-R90B to the blue-grey family. Their light reflectance values are nearly the same — 18 vs 19 — so neither will read significantly brighter or darker than the other. Where Nile Blue leans blue, S 5010-R90B reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 19.9 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Nile Blue vs S 5010-R90B Simulated Comparison
5 simulated room previews — drag the slider on each to see Nile Blue on one side and S 5010-R90B 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.
