Blue SpruceBenjamin MoorevsCastle GateBenjamin MooreΔE 17.0 — Distinct difference

Blue Spruce and Castle Gate come from the same Benjamin Moore collection. Blue Spruce reads as blue-grey, while Castle Gate reads as grey — two distinct hue families, not close cousins. The 9-point LRV gap — 26 for Castle Gate vs 17 for Blue Spruce — means Castle Gate will open up a space more effectively. Where Blue Spruce leans blue, Castle Gate reads red — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 17.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
