At Sea vs Copper Patina
Both from Benjamin Moore's palette. These are both blue-greens, so the question isn't which hue to choose — it's where within blue-green to land. At Sea (LRV 71) reflects noticeably more light than Copper Patina (LRV 61), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Both lean green, so they'll behave similarly in mixed or changing light conditions. The ΔE 6.3 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.
