Blue grey vs Piazza
Blue grey (RAL Classic) and Piazza (Tikkurila) come from different manufacturers. Blue grey reads as blue-grey, while Piazza reads as beige-greige — two distinct hue families, not close cousins. The 49-point LRV gap — 65 for Piazza vs 16 for Blue grey — means Piazza will open up a space more effectively. A ΔE of 42.9 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Blue grey vs Piazza in Real Spaces
2 real rooms side by side. Seeing Blue grey and Piazza in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Piazza reflects noticeably more light off the walls, making the space read more open than Blue grey.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Piazza returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Blue grey 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.
