Subtle Blue vs Ammonite
Where Subtle Blue belongs to PPG's range, Ammonite is a Farrow & Ball color. Subtle Blue (LRV 75) reflects noticeably more light than Ammonite (LRV 69), a difference of 6 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
Subtle Blue vs Ammonite Color Comparison
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.
