North Sea vs Black Opal
Where North Sea belongs to Benjamin Moore's range, Black Opal is a Dulux color. 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 (6 vs 6), so they'll read as similarly Dark in most lighting conditions. North Sea runs blue while Black Opal is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
