Copley Gray vs Thames Fog
Where Copley Gray belongs to Benjamin Moore's range, Thames Fog is a Valspar color. Copley Gray reads as greige-grey, while Thames Fog reads as grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (26 vs 27), so they'll read as similarly Medium in most lighting conditions. The ΔE 4.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Copley Gray vs Thames Fog in Real Spaces
3 real rooms side by side. Copley Gray and Thames Fog are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.

Copley Gray vs Thames Fog Simulated Comparison
5 simulated room previews — drag the slider on each to see Copley Gray on one side and Thames Fog on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
