<li><b>"random"</b> will generate a random color</li>

<li><b>object</b> can override any of the parameters</li>
<li><b>array</b> of colours for a neopixel rgb strip - either name,name,... or r,g,b,r,g,b,... where r,g,b are 0 to 255.</li>
</ul>
<p>If using a neopixel strip it <i>must</i> be wired to the red or R channel of the blinkstick.</p>
<p>An object payload can override any of the settings on the node. Omitted parameters are left intact. For example:</p>
<pre>
{ 'color': 'blue' }
