Nautilus Shell vs Agreeable Gray
Where Nautilus Shell belongs to Benjamin Moore's range, Agreeable Gray is a Sherwin-Williams color. Nautilus Shell reads as beige, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. Nautilus Shell (LRV 74) reflects noticeably more light than Agreeable Gray (LRV 60), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Nautilus Shell runs red while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 11.6, 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.
