Nile Blue vs Ammonite
Where Nile Blue belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Nile Blue reads as blue, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Nile Blue (LRV 18), a difference of 51 points that becomes especially apparent in rooms with limited natural light. Nile Blue runs blue while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 50.6, 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 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

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.
