Blue Horizon vs Opera Glass
Both from Sherwin-Williams's palette. Hue-wise, Blue Horizon belongs to the blue family and Opera Glass to the green family. Opera Glass (LRV 86) reflects noticeably more light than Blue Horizon (LRV 78), a difference of 8 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. The ΔE 4.5 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.
