Wetherburn's Blue vs Grey Blue
Wetherburn's Blue (Benjamin Moore) and Grey Blue (RAL Classic) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 16-point LRV gap — 24 for Wetherburn's Blue vs 7 for Grey Blue — means Wetherburn's Blue will open up a space more effectively. A ΔE of 22.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.
