Blue Macaw vs S 5010-R90B
Blue Macaw (Benjamin Moore) and S 5010-R90B (NCS) come from different manufacturers. Blue Macaw reads as blue, while S 5010-R90B reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 18 vs 19 — so neither will read significantly brighter or darker than the other. Where Blue Macaw leans blue, S 5010-R90B reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 26.4 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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