Sea Serpent vs White Duck
Both from Sherwin-Williams's palette. Sea Serpent reads as blue, while White Duck reads as beige-greige — two distinct hue families, not close cousins. White Duck (LRV 74) reflects noticeably more light than Sea Serpent (LRV 7), a difference of 67 points that becomes especially apparent in rooms with limited natural light. Sea Serpent runs cool while White Duck is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 59.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

8 real rooms side by side. Seeing Sea Serpent and White Duck 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

Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that White Duck will make the room feel meaningfully brighter than Sea Serpent would.

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.
