title: Octave: how can I colorize an isosurface?
body: <p>I'm trying to make an isosurface be colorized by pretty much anything. The details don't matter, but at the moment it's a single-color green blob. I've tried using <code>isocolors</code>, and the best I could get was that the whole thing turned a shade of teal instead.</p>
