Polished Concrete vs Thames Fog
Where Polished Concrete belongs to Sherwin-Williams's range, Thames Fog is a Valspar color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Polished Concrete (LRV 32) reflects noticeably more light than Thames Fog (LRV 27), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 7.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
