Amazing Gray vs Sea Mariner
Amazing Gray and Sea Mariner come from the same Sherwin-Williams collection. Hue-wise, Amazing Gray belongs to the greige-grey family and Sea Mariner to the blue-grey family. The 40-point LRV gap — 47 for Amazing Gray vs 7 for Sea Mariner — means Amazing Gray will open up a space more effectively. Where Amazing Gray leans warm, Sea Mariner reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 45.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Amazing Gray vs Sea Mariner in Real Spaces
2 real rooms side by side. Seeing Amazing Gray and Sea Mariner in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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 Amazing Gray will make the room feel meaningfully brighter than Sea Mariner would.
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. Amazing Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
