1 The colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, natural oak, grey oak, walnut, patina grey and plain aluminium reflect natural tones and are therefore subject to slight variations in colour, which give the products their unmistakable character.

  • The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA colour and, under certain circumstances, may not reflect the subjective perception of the colour. 
  • Above all for colour quality P.10, it is almost impossible to define values due to the surface structure. Furthermore, the colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, walnut, grey oak, natural oak and patina grey reflect natural colourings that are composed of several colour tones.
