<h2>Syntax</h2>
<pre class="synopsis"><span class="command"><strong>FLsetColor</strong></span> ired, igreen, iblue, ihandle</pre>
</div>
<div class="refsect1" title="Initialization">
<a id="idp21940504"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>ired</em></span> -- The red color of the target widget. The range for each RGB component is 0-255
</p>
<p>
<span class="emphasis"><em>igreen</em></span> -- The green color of the target widget. The range for each RGB component is 0-255
</p>
<p>
<span class="emphasis"><em>iblue</em></span> -- The blue color of the target widget. The range for each RGB component is 0-255
</p>
<p>
<span class="emphasis"><em>ihandle</em></span> -- an integer number (used as unique identifier) taken from the output of a previously located widget opcode (which corresponds to the target widget). It is used to unequivocally identify the widget when modifying its appearance with this class of opcodes. The user must not set the <span class="emphasis"><em>ihandle</em></span> value directly, otherwise a Csound crash will occur.
