Ammonite vs Mushroom
Where Ammonite belongs to Farrow & Ball's range, Mushroom is a Sherwin-Williams color. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Ammonite (LRV 69) reflects noticeably more light than Mushroom (LRV 57), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. The ΔE 7.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison 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.
