Ammonite vs Sky High
Where Ammonite belongs to Farrow & Ball's range, Sky High is a Sherwin-Williams color. Ammonite reads as beige-greige, while Sky High reads as blue — two distinct hue families, not close cousins. Sky High (LRV 78) reflects noticeably more light than Ammonite (LRV 69), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Ammonite runs warm while Sky High is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Ammonite vs Sky High in Real Spaces
2 real rooms side by side. Ammonite and Sky High are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Sky High will make the room feel meaningfully brighter than Ammonite would.

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.
