Hi,
just playing around with spot colors and run into this problem.
tested with 23.04.2012 and ??.11.2011, same result. the color definition
leads to an invalid pdf.
% multitone.tex----
\nopdfcompression
\setuppagenumber[state=stop]
\definemultitonecolor[combicolor] [blue=.12,yellow=.28]
[c=.1,m=.1,y=.3,k=.1]
\starttext
\null
\stoptext
%------------------
I also attached the original example (spot.tex).
Best wishes, Peter

You need to define the colorants as spot color first. It happens that
yellow is an official built in colorant but blue isn't.
\nopdfcompression
\definecolor [xcyan] [c=1]
\definecolor [xmagenta][m=1]
\definecolor [xyellow] [y=1]
\definespotcolor [scyan] [xcyan] [p=1]
\definespotcolor [smagenta][xmagenta][p=1]
\definespotcolor [syellow] [xyellow] [p=1]
\definemultitonecolor[scombi]
[xcyan=.2,xmagenta=.4,xyellow=.6][c=.2,m=.4,y=.6]
\startTEXpage
\hbox \bgroup
\blackrule[color=scyan, width=1cm,height=1cm,depth=0cm]%
\blackrule[color=smagenta,width=1cm,height=1cm,depth=0cm]%
\blackrule[color=syellow, width=1cm,height=1cm,depth=0cm]%
\blackrule[color=scombi, width=1cm,height=1cm,depth=0cm]%
\egroup
\stopTEXpage

OK. I simply used the multitone example (spot.tex) from the Wiki.
http://wiki.contextgarden.net/Colors#Multitones
I have updated the outdated example (12/2004), but I can't tell much
about spot or multitone colors (never used them).
@all: feel free to add some sentences
Peter
