/* ==========================================================================
   Colour palette
   --------------------------------------------------------------------------
   Base colours are taken from the Open Furniture Culture worksheets
   (Werkblätter). Derived colours apply the same deviation that separates
   the worksheet colours from the former Riso palette: chroma reduced by
   about a quarter, dark tones lifted, hue kept.

   Screen values are sRGB. CMYK values refer to FOGRA39 (ISO Coated v2,
   coated paper), relative colorimetric with black point compensation.
   Delta E is the expected screen-to-print deviation; above about 3 the
   difference is visible side by side.

   Not every colour is in use yet. Keep them here as the single source.
