Stone Mill vs RAL 850-4 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 — Stone Mill gives the walls a little more lift.

Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Stone Mill reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
