<p>A color is a standard color name in quotes. It is normally specified as an <a href="http://www.w3.org/TR/SVG/types.html#ColorKeywords">SVG color name</a>. These names include colors like "red", "green" and "lightsteelblue".</p>
<p>If the color you want isn't part of this list, colors can also be specified in hexidecimal triplets or quads that take the form <tt>"#RRGGBB"</tt> and <tt>"#AARRGGBB"</tt> respectively. For example, the color red corresponds to a triplet of <tt>"#FF0000"</tt> and a slightly transparent blue to a quad of <tt>"#800000FF"</tt>.</p>
<p>Example:</p>
