Indigo Batik vs Sea Mariner

Indigo Batik and Sea Mariner come from the same Sherwin-Williams collection. Indigo Batik reads as blue, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 8 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. ΔE 6.9 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Indigo Batik vs Sea Mariner in Real Spaces

2 real rooms side by side. Indigo Batik and Sea Mariner 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.

Mudroom

In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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.
