One place I worked did at one point use coloured pencils in place of hatches for differnet inclusions (red for brick/tile, yellow for mortar, blue for imported stone and green for chalk)
I too worked on a site in the early 80s where we had what looked like conventional coloured pencils, but when you licked the end they turned into 'watercolour' pencils. Made by a French company I think....
I am not even going to think about the damage to my health licking coloured pencils on London building sites has done....
