Monorail Silver vs Thames Fog

The 22-point LRV gap — 50 for Monorail Silver vs 27 for Thames Fog — means Monorail Silver will open up a space more effectively. A ΔE of 18.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Monorail Silver vs Thames Fog in Real Spaces
3 real rooms side by side. Seeing Monorail Silver 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. Monorail Silver reflects noticeably more light off the walls, making the space read more open than Thames Fog.
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. Monorail Silver 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. Monorail Silver returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
