Mystical Blue vs Rain Sky
Where Mystical Blue belongs to Benjamin Moore's range, Rain Sky is a Jotun color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Mystical Blue (LRV 73) reflects noticeably more light than Rain Sky (LRV 69), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Mystical Blue runs blue while Rain Sky is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.6 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.
