Regent Green vs Rookwood Shutter Green
Where Regent Green belongs to Benjamin Moore's range, Rookwood Shutter Green is a Sherwin-Williams color. These are both blue-greens, so the question isn't which hue to choose — it's where within blue-green to land. They have nearly identical light reflectance values (6 vs 4), so they'll read as similarly Dark in most lighting conditions. Regent Green runs blue while Rookwood Shutter Green is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Regent Green vs Rookwood Shutter Green in Real Spaces
4 real rooms side by side. Regent Green and Rookwood Shutter Green 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
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. The distinction reads clearly at room scale, making the choice between them concrete.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

Regent Green vs Rookwood Shutter Green Simulated Comparison
5 simulated room previews — drag the slider on each to see Regent Green on one side and Rookwood Shutter Green on the other.
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.
