Where Coastline belongs to Benjamin Moore's range, RAL 810-1 is a RAL Effect color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (34 vs 33), so they'll read as similarly Medium in most lighting conditions. The ΔE 3.9 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.
