Gem Silica vs Shamrock Green
Both from Behr's palette. These are both greens, so the question isn't which hue to choose — it's where within green to land. Gem Silica (LRV 39) reflects noticeably more light than Shamrock Green (LRV 25), a difference of 15 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. With a ΔE of 13.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
