Colorado Gray vs St. John Blue
Both from Benjamin Moore's palette. Colorado Gray reads as blue-grey, while St. John Blue reads as blue — two distinct hue families, not close cousins. Colorado Gray (LRV 44) reflects noticeably more light than St. John Blue (LRV 34), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.5 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.
