Greens vs Shamrock
Both from Sherwin-Williams's palette. These are both greens, so the question isn't which hue to choose — it's where within green to land. Greens (LRV 10) reflects noticeably more light than Shamrock (LRV 6), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 13.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Greens vs Shamrock in Real Spaces
3 real rooms side by side. Seeing Greens and Shamrock in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — Greens gives the walls a little more lift.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Greens reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
