<h3>RGB Slider</h3>
<p>
The RGB slider implements three slider controls to generate a
RGB color. The background color of each slider is also
dynamically modified to reflect the colors that could be
generated by moving a single slider.
</p>
<strong>The logger is paused for performance reasons. Click "Resume" to re-enable it.</strong>
