Hague Blue vs Sea Serpent
Hague Blue (Farrow & Ball) and Sea Serpent (Sherwin-Williams) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Their light reflectance values are nearly the same — 7 vs 7 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 1.8 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Hague Blue vs Sea Serpent in Real Spaces
6 real rooms side by side. Hague Blue and Sea Serpent 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.
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. 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.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
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.

Hague Blue vs Sea Serpent Simulated Comparison
5 simulated room previews — drag the slider on each to see Hague Blue on one side and Sea Serpent 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.
