French Gray vs Thunderbird in Real Spaces
6 real rooms side by side. Seeing French Gray and Thunderbird 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. French Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that French Gray will make the room feel meaningfully brighter than Thunderbird would.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. French Gray reflects noticeably more light off the walls, making the space read more open than Thunderbird.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that French Gray will make the room feel meaningfully brighter than Thunderbird would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that French Gray will make the room feel meaningfully brighter than Thunderbird would.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. French Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
