Stratton Blue vs Rosemary Leaf
Stratton Blue (Benjamin Moore) and Rosemary Leaf (Dulux) come from different manufacturers. These are both blue-greens, so the question isn't which hue to choose — it's where within blue-green to land. Their light reflectance values are nearly the same — 38 vs 40 — so neither will read significantly brighter or darker than the other. Where Stratton Blue leans green, Rosemary Leaf reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 3.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Stratton Blue vs Rosemary Leaf in Real Spaces
4 real rooms side by side. Stratton Blue and Rosemary Leaf 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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Stratton Blue vs Rosemary Leaf Simulated Comparison
5 simulated room previews — drag the slider on each to see Stratton Blue on one side and Rosemary Leaf 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.
