Greenhouse vs Shamrock
Greenhouse and Shamrock come from the same Sherwin-Williams collection. These are both greens, so the question isn't which hue to choose — it's where within green to land. The NaN-point LRV gap — 6 for Shamrock vs NaN for Greenhouse — means Shamrock will open up a space more effectively. Where Greenhouse leans warm, Shamrock reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 3.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Greenhouse vs Shamrock in Real Spaces
3 real rooms side by side. Greenhouse and Shamrock are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Greenhouse brings more warmth to the space, while Shamrock keeps things cooler and crisper.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Shamrock reads more restrained here, while Greenhouse adds a sense of enclosure and warmth.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Greenhouse brings more warmth to the space, while Shamrock keeps things cooler and crisper.

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.
