Storm Warning vs Thames Fog
Storm Warning (Sherwin-Williams) and Thames Fog (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 14-point LRV gap — 27 for Thames Fog vs 14 for Storm Warning — means Thames Fog will open up a space more effectively. A ΔE of 16.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.
