I have never used the sidebar mechanism, but there is a "rulecolor" option in setupsidebar.  Maybe that's what you're looking for.

You can look up the commands and their options in "i-context.pdf" file.

It is good to know the commnad "\startsidebar … \stopsidebar” because I used the same style bar by defining a frame and overlay.
Here is  a question: Is it possible to change the color of the bar or any other options?
There is no commnad like “\setupsidebar” in the wiki.

Thank you.

Best regards,

Dalyoung
