Gypsum vs Piazza
Where Gypsum belongs to Sherwin-Williams's range, Piazza is a Tikkurila color. Gypsum reads as white, while Piazza reads as beige-greige — two distinct hue families, not close cousins. Gypsum (LRV 82) reflects noticeably more light than Piazza (LRV 65), a difference of 17 points that becomes especially apparent in rooms with limited natural light. The ΔE 9.3 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.
Gypsum vs Piazza in Real Spaces
2 real rooms side by side. Gypsum and Piazza 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 Gypsum will make the room feel meaningfully brighter than Piazza would.

Gypsum vs Piazza Simulated Comparison
5 simulated room previews — drag the slider on each to see Gypsum on one side and Piazza on the other.
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.
