Thats how itemgroup are configured. You cannot mix assignments (key=value) 
with options.

You can use

\setupitemgroup
     [article]
     [command=\blank]

(in this case you can remove the second configuration (the one with broad, 
fit) or explicitly set width=0).

Why do you expect \setuphead to change the way itemgroups behave? Use


\setupitemgroup
    [article]
    [color=...]
