Blue Iris vs Piazza
Where Blue Iris belongs to Sherwin-Williams's range, Piazza is a Tikkurila color. Blue Iris reads as blue-grey, while Piazza reads as beige-greige — two distinct hue families, not close cousins. Blue Iris (LRV 73) reflects noticeably more light than Piazza (LRV 65), a difference of 8 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
