Thunder Gray vs Sea Grove
Thunder Gray (Sherwin-Williams) and Sea Grove (Valspar) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 7-point LRV gap — 15 for Sea Grove vs 9 for Thunder Gray — means Sea Grove will open up a space more effectively. A ΔE of 11.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.
