RAL 540-6 vs Agreeable Gray in Real Spaces
6 real rooms side by side. Seeing RAL 540-6 and Agreeable Gray 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. Agreeable 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 Agreeable Gray will make the room feel meaningfully brighter than RAL 540-6 would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Agreeable Gray will make the room feel meaningfully brighter than RAL 540-6 would.
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 Agreeable Gray will make the room feel meaningfully brighter than RAL 540-6 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 Agreeable Gray will make the room feel meaningfully brighter than RAL 540-6 would.
