Big Dipper vs Riverway
Big Dipper and Riverway come from the same Sherwin-Williams collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 9-point LRV gap — 16 for Riverway vs 6 for Big Dipper — means Riverway will open up a space more effectively. Where Big Dipper leans neutral, Riverway reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes.
