A supplementary question, if I may ? The PdfTeX reference manual as found at Tug.Org has Chapter Eight entitled "Graphics and color", yet the chapter seems not to mention colour at all and focuses solely on graphics. Section 7.12 says "\pdfliteral [ <pdfliteral spec> ] <general text> Like \special in normal TEX, this command inserts raw pdf code into the output. This allows support of color and text transformation." but as far as I can tell, there are no examples of suitable parameters for affecting the colour of (e.g.) rendered text. May I ask if there is a supplementary manual that defines how colour is to be programmed through PdfTeX ?
Again, it's implemented in pdftex.def, look for \pdfcolorstack... Color parameters are specified in the PDF specification. Yours sincerely Heiko Oberdiek --
