Hardwick White vs Sea Serpent
Hardwick White (Farrow & Ball) and Sea Serpent (Sherwin-Williams) come from different manufacturers. Hardwick White reads as greige-grey, while Sea Serpent reads as blue — two distinct hue families, not close cousins. The 37-point LRV gap — 44 for Hardwick White vs 7 for Sea Serpent — means Hardwick White will open up a space more effectively. Where Hardwick White leans warm, Sea Serpent reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 43.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 9 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Hardwick White vs Sea Serpent in Real Spaces
9 real rooms side by side. Seeing Hardwick White and Sea Serpent 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
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. Hardwick White reflects noticeably more light off the walls, making the space read more open than Sea Serpent.
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. Hardwick White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Hardwick White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Hardwick White will make the room feel meaningfully brighter than Sea Serpent would.
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. Hardwick White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Hardwick White will make the room feel meaningfully brighter than Sea Serpent would.
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. Hardwick White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Hardwick White reflects noticeably more light off the walls, making the space read more open than Sea Serpent.
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. Hardwick White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Hardwick White vs Sea Serpent Simulated Comparison
5 simulated room previews — drag the slider on each to see Hardwick White 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.
