Wales Gray vs Thames Fog
Wales Gray (Benjamin Moore) and Thames Fog (Valspar) come from different manufacturers. Wales Gray reads as blue-grey, while Thames Fog reads as grey — two distinct hue families, not close cousins. The 26-point LRV gap — 54 for Wales Gray vs 27 for Thames Fog — means Wales Gray will open up a space more effectively. A ΔE of 20.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Wales Gray vs Thames Fog in Real Spaces
5 real rooms side by side. Seeing Wales Gray and Thames Fog in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Wales Gray reflects noticeably more light off the walls, making the space read more open than Thames Fog.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Wales Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Wales Gray will make the room feel meaningfully brighter than Thames Fog would.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Wales Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Wales Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Wales Gray vs Thames Fog Simulated Comparison
5 simulated room previews — drag the slider on each to see Wales 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.
