<h2 id="details">Detailed Description</h2>
<p>The <a href="qgraphicscolorizeeffect.html">QGraphicsColorizeEffect</a> class provides a colorize effect.</p>
<p>A colorize effect renders the source with a tint of its <a href="qgraphicscolorizeeffect.html#color-prop">color</a>(). The color can be modified using the <a href="qgraphicscolorizeeffect.html#color-prop">setColor</a>() function.</p>
<p>By default, the color is light blue (<a href="../qtgui/qcolor.html">QColor</a>(0, 0, 192)).</p>
