Hi,
in MkIV there is a problem when I set tints for a color.
This is a complete minimal example of my setup:
\setupcolors[state=start,rgb=no,cmyk=yes,spot=yes] % rgb= no needed in
MkII
\setupcolor [hex]
\definecolor[PantoneOneEightSeven][h=C40F2F,e=Pantone 187 U]
\definespotcolor[dtkred] [PantoneOneEightSeven][p=1.0]
\definespotcolor[dtkredlight][PantoneOneEightSeven][p=0.7]
\starttext
\blackrule[width=4cm,height=4cm,color=dtkred,]
\blackrule[width=4cm,height=4cm,color=dtkredlight]
\stoptext
I could also reproduce it with a short setup:
\setupcolors[state=start,rgb=no] % rgb= no needed in MkII
\definespotcolor[dtkred] [red][p=1.0]
\definespotcolor[dtkredlight][red][p=0.7]
\starttext
\blackrule[width=4cm,height=4cm,color=dtkred,]
\blackrule[width=4cm,height=4cm,color=dtkredlight]
\stoptext
With the setting rgb=yes the color dtkred is correct in the output
but dtkredlight is darker than dtkred, with the setting rgb=no
dtkred is black in my document.
