Hi there, I'm trying to get to grips with all these colours in ConTeXt and MetaFun ... What I'd like to get is a document with CMYK and spot colours only, so here's my attempt: --- \enableregime[utf] \noheaderandfooterlines \setupcolors[cmyk=yes,rgb=no,spot=yes,state=start] \definecolor[PANTONE328CS] [c=1,m=0,y=.52,k=.11] \definecolor[PANTONE428CS] [c=0,m=.02,y=.09,k=.14] \definecolor[my_green] [PANTONE328CS][p=1] \definecolor[my_lightgreen] [PANTONE328CS][p=.5] \definecolor[my_grey] [PANTONE428CS][p=1] \definecolor[my_mediumgrey] [PANTONE428CS][p=.8] \definecolor[my_lightgrey] [PANTONE428CS][p=.5] \setuppapersize[A4][A4] \starttext \section{CMYK colours} \startcolor[cyan] \input ward \stopcolor \startcolor[magenta] \input ward \stopcolor \startcolor[yellow] \input ward \stopcolor \section{Spot colours} \startcolor[my_green] \input ward \stopcolor \startcolor[my_lightgreen] \input ward \stopcolor \startcolor[my_grey] \input ward \stopcolor \startcolor[my_mediumgrey] \input ward \stopcolor \startcolor[my_lightgrey] \input ward \stopcolor \stoptext --- However, I encountered a few oddities. I could separate the channels c, m, y, k via texexec --separation=c file.tex etc. but on the individual channels c, m and y the black headings as well as all spot colours kept appearing. Shouldn't the cyan channel contain only cyan and nothing else? Also, I have no clue how to separate the spot colours ... Both texexec --separation=PANTONE328CS file.tex and texexec --separation=my_green file.tex spilled out tons of error messages. What could I improve to make this work? Cheerio, Oliver
