</h1><div class="doc"><p><code><a href="Graphics-UI-Gtk-Selectors-HSV.html#t:HSV">HSV</a></code> is the 'color wheel' part of a complete color selector widget. It
allows to select a color by determining its <code><a href="Graphics-UI-Gtk-Selectors-HSV.html#t:HSV">HSV</a></code> components in an intuitive
way. Moving the selection around the outer ring changes the hue, and moving
the selection point inside the inner triangle changes value and saturation.
