Put the following code into your preamble if you cannot change the 
PostScript code yourself.

\AtBeginDocument{%
   \special{ps:
     /setcmykcolor { exch 0.11 mul add
                     exch 0.59 mul add
                     exch 0.3 mul add
                     dup 1 gt { pop 1 }  if neg 1 add setgray } def
     /setrgbcolor { 0.11 mul
                    exch 0.59 mul add
                    exch 0.3 mul add setgray } def
     /sethsbcolor { /b exch def /s exch def 6 mul dup cvi dup /i exch 
def sub /f exch def
                    /F [[0 1 f sub 1][f 0 1][1 0 1 f sub][1 f 0][1 f sub 
1 0][0 1 f][0 1 1]] def
                    F i get { s mul neg 1 add b mul} forall
                    0.11 mul
                    exch 0.59 mul add
                    exch 0.3 mul add setgray } def
   }

If you want to have yellow lighter than blue, redefine the
colors in the preamble with \definecolor{yellow}{rgb}{...}

the distiller is an external and commercial program of adobe for
converting a ps file into a pdf.
