Undertone
Reads as a warm red with a pink undertone showing through, especially in daylight. Pair trim and adjacent colours to either calm or amplify that undertone.

About RAL 040 30 40
What is a RAL colour?
RAL is the European colour-matching standard used to specify exact colours for paints and coatings. Each code — like RAL 040 30 40 from the RAL Design System — maps to one defined colour, 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.
Matching RAL 040 30 40 on interior walls
RAL is defined for industrial coatings, not interior wall paint — so to paint a room in this colour you match it to a real interior brand.
