Smoky Slate vs RAL 210-M in Real Spaces

Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — RAL 210-M gives the walls a little more lift.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. RAL 210-M reads slightly lighter here — a subtle but real difference in how open the space feels.
