Blue Grass vs Ammonite
Where Blue Grass belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Blue Grass reads as blue-green, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. Ammonite (LRV 69) reflects noticeably more light than Blue Grass (LRV 60), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Blue Grass runs cool while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

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.
