Siren vs Thames Fog
Siren (Cloverdale Paint) and Thames Fog (Valspar) come from different manufacturers. Siren reads as pink-red, while Thames Fog reads as grey — two distinct hue families, not close cousins. The 16-point LRV gap — 27 for Thames Fog vs 11 for Siren — means Thames Fog will open up a space more effectively. A ΔE of 47.7 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Siren vs Thames Fog in Real Spaces
4 real rooms side by side. Seeing Siren 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. Thames Fog reflects noticeably more light off the walls, making the space read more open than Siren.
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. Thames Fog 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 Thames Fog will make the room feel meaningfully brighter than Siren 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. Thames Fog returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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