Ok, I can access the wiki via Tor and found
\somenamedheadnumber{chapter}{current}
\somenamedheadnumber{chapter}{last}
or
\someheadnumber[chapter][current]
\someheadnumber[chapter][last]
What’s the difference?
And even if I use \definecolor within a setup, I get the same color for
every chapter – how and where must I delay expansion?
\usemodule[visual]
\startsetups[MyChapterSetup]
\definecolor[MyChapterColor][h={360*\somenamedheadnumber{chapter}{current}/\somenamedheadnumber{chapter}{last}},s=1,v=1]
\definecolor[fakerulecolor][MyChapterColor]
\setuphead[chapter][color=MyChapterColor]
\stopsetups
\unexpanded\def\MyChapter#1{
\setup{MyChapterSetup}
\color[MyChapterColor]{#1}
}
\setuphead[chapter][page=no,textcommand=\MyChapter]
\starttext
\dorecurse{20}{
\chapter{\fakewords{1}{5}}
\fakewords{10}{50}
}
\stoptext
