Ionic Ivory vs Sea Mariner
Both from Sherwin-Williams's palette. Ionic Ivory reads as beige-yellow, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Ionic Ivory (LRV 74) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 67 points that becomes especially apparent in rooms with limited natural light. Ionic Ivory runs warm while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 61.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
