Halcyon Green vs Marine
Both are Sherwin-Williams colors. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 38 and 36, they'll behave almost identically in terms of how much light they reflect back into a room. They share a cool quality — useful to know if you're layering them in the same space. With a ΔE of 2.2, the difference is subtle — you'd need them side by side to reliably tell them apart.

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.
