Horizon Gray vs Piazza
Where Horizon Gray belongs to Benjamin Moore's range, Piazza is a Tikkurila color. Horizon Gray reads as greige-grey, while Piazza reads as beige-greige — two distinct hue families, not close cousins. Piazza (LRV 65) reflects noticeably more light than Horizon Gray (LRV 51), a difference of 14 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.9 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.
