Castle Walls vs Rushing River
Both from Benjamin Moore's palette. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. Castle Walls (LRV 41) reflects noticeably more light than Rushing River (LRV 30), 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 8.4 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.
