The <code>section-3</code> corresponds to <code>section</code>. Similarly,
<code>section-1</code> corresponds to <code>part</code>, <code>section-2</code> corresponds to <code>chapter</code> and so on.
===Using colors in chapters and sections===
If you want you may have colors on your document's chapters or sections.
To do that you should use <code>\setuphead</code>.
Take a look at the following example:
<texcode>
\setupcolors[state=start] % Important. You won't have colors without it.
\setuphead[chapter][header=empty] % Chapter pages won't have headers
\setupheadertexts[][chapter] % The header will be the chapter's name
\starttext
\completecontent
\chapter{Black chapter 1}
\setuphead[section][color=darkcyan] % This is how you change your chapter's color.
\section{Dark cyan section 1.1}
\page

\setuphead[chapter][color=darkgreen]

</texcode>
