Celtic Blue vs Lakeside
Where Celtic Blue belongs to Benjamin Moore's range, Lakeside is a Sherwin-Williams color. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Lakeside (LRV 47) reflects noticeably more light than Celtic Blue (LRV 0), a difference of 47 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. At ΔE 1.4, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. 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.
