/* Tromboneworkshop.nl — huisstijl
   Zakelijk en chique: donkere ondergrond, warm papierwit, messing als enige accentkleur
   (het metaal van een echte trombone). De gekleurde ringen blijven alleen in het logo;
   het speelse karakter hoort bij mr. pBone.
   Layout: ruime, rustige secties met dunne messing lijnen en een asymmetrisch raster. */
