88<p>AcquireColorCache() caches one or more color configurations which provides a mapping between color attributes and a color name.</p>

176
177<p>ListColorInfo() lists color names to the specified file.  Color names are a convenience.  Rather than defining a color by its red, green, and blue intensities just use a color name such as white, blue, or yellow.</p>
178

192
193<h2><a href="../../api/MagickCore/color_8c.html" id="QueryColorname">QueryColorname</a></h2>
194
195<p>QueryColorname() returns a named color for the given color intensity. If an exact match is not found, a hex value is returned instead.  For example an intensity of rgb:(0,0,0) returns black whereas rgb:(223,223,223) returns #dfdfdf.</p>
196
197<p>UPDATE: the 'image' argument is no longer needed as all information should have been preset using GetPixelInfo().</p>
198
199<p>The format of the QueryColorname method is:</p>

201<pre class="text">
