Spring Thaw vs Blue Iris
Spring Thaw is a PPG color while Blue Iris comes from Sherwin-Williams. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 71 and 73, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.0, the difference is subtle — you'd need them side by side to reliably tell them apart.
