Quiet · Versatile

Dark Pink gets out of the way so the architecture and the people in the room do the work. The right neutral is never a default — it reads warm or cool, dusty or sharp depending on its undertone, and that undertone is what makes or breaks the room.

What is a RAL color?

RAL is the European color-matching standard used to specify exact colors for paints and coatings. Each code — like RAL 310 40 10 from the RAL Design System — maps to one defined color, so a manufacturer or painter anywhere produces the identical result. It's used first and foremost on window frames, doors, façades, gates, railings and powder-coated metalwork.
