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.
