Anonymous vs Thames Fog
Where Anonymous 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. Thames Fog (LRV 27) reflects noticeably more light than Anonymous (LRV 20), a difference of 8 points that becomes especially apparent in rooms with limited natural light. The ΔE 8.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
