Limestone vs Thames Fog
Limestone is a Sherwin-Williams color while Thames Fog comes from Valspar. These are both greys, so the question isn't which hue to choose — it's where within grey to land. At LRV 27 vs 13, Thames Fog will read as the brighter of the two — a 14-point gap that matters most in north-facing or low-light rooms. At ΔE 16.7, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.
