It use the tiling number 25. This is a 6 colour pattern.
You need to provide a colour_map with 12 entries : 6 for the faces of 
the tiles and 6 for the grout or space between the faces.
You may omit the grout entry if you want.
If you skip some entries, then you'll get faces with the same colour.

Something like this :
colour_map{
  [0   rgb<1,0,0>][1/6-0.001 rgb 0]
  [1/6 rgb<0,1,0>][2/6-0.001 rgb 0]
  [2/6 rgb<0,0,1>][3/6-0.001 rgb 0]
  [3/6 rgb<1,1,0>][4/6-0.001 rgb 0]
  [4/6 rgb<1,0,1>][5/6-0.001 rgb 0]
  [5/6 rgb<0,1,1>][0.999 rgb 0]
}
