Clean Slate vs Piazza
Where Clean Slate belongs to Sherwin-Williams's range, Piazza is a Tikkurila color. Clean Slate reads as blue-green, while Piazza reads as beige-greige — two distinct hue families, not close cousins. Clean Slate (LRV 76) reflects noticeably more light than Piazza (LRV 65), a difference of 11 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.
