Blue Spruce vs Thames Fog in Real Spaces
2 real rooms side by side. Seeing Blue Spruce 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.
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 Thames Fog will make the room feel meaningfully brighter than Blue Spruce would.
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. Thames Fog returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Blue Spruce 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.
