RAL 770-4 vs Iron Ore in Real Spaces
5 real rooms side by side. Seeing RAL 770-4 and Iron Ore 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. RAL 770-4 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 RAL 770-4 will make the room feel meaningfully brighter than Iron Ore 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 RAL 770-4 will make the room feel meaningfully brighter than Iron Ore 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 RAL 770-4 will make the room feel meaningfully brighter than Iron Ore would.
