<p>"Red", "Green", and "Blue" are the intensities of those colors. In combination,
they represent the colorspace.</p>
<p>Matplotlib draws Artists based on the <code class="docutils literal notranslate"><span class="pre">zorder</span></code> parameter. If there are no
specified values, Matplotlib defaults to the order of the Artists added to the
Axes.</p>
<p>The alpha for an Artist controls opacity. It indicates how the RGB color of the
new Artist combines with RGB colors already on the Axes.</p>
<p>The two Artists combine with alpha compositing. Matplotlib uses the equation
below to compute the result of blending a new Artist.</p>

<p>Alpha of 1 indicates the new Artist completely covers the previous color.
Alpha of 0 for top color is not visible; however, it contributes to blending
for intermediate values as the cumulative result of all previous Artists. The
following table contains examples.</p>

<span id="xkcd-colors"></span><h2>Comparison between X11/CSS4 and xkcd colors<a class="headerlink" href="#comparison-between-x11-css4-and-xkcd-colors" title="Permalink to this headline">¶</a></h2>
<p>The xkcd colors come from a <a class="reference external" href="https://blog.xkcd.com/2010/05/03/color-survey-results/">user survey conducted by the webcomic xkcd</a>.</p>
<p>95 out of the 148 X11/CSS4 color names also appear in the xkcd color survey.
Almost all of them map to different color values in the X11/CSS4 and in
the xkcd palette. Only 'black', 'white' and 'cyan' are identical.</p>
<p>For example, <code class="docutils literal notranslate"><span class="pre">'blue'</span></code> maps to <code class="docutils literal notranslate"><span class="pre">'#0000FF'</span></code> whereas <code class="docutils literal notranslate"><span class="pre">'xkcd:blue'</span></code> maps to
<code class="docutils literal notranslate"><span class="pre">'#0343DF'</span></code>. Due to these name collisions, all xkcd colors have the
<code class="docutils literal notranslate"><span class="pre">'xkcd:'</span></code> prefix.</p>
<p>The visual below shows name collisions. Color names where color values agree
are in bold.</p>
