43 * Basic drawing color for graphics, not text. For the latter, use the
\r
44 * fontcolor attribute. For edges, the value can either be a single color or
\r
45 * a colorList. In the latter case, the edge is drawn using parallel splines
\r
46 * or lines, one for each color in the list, in the order given. The head
\r
47 * arrow, if any, is drawn using the first color in the list, and the tail
\r
48 * arrow, if any, the second color. This supports the common case of drawing
\r
49 * opposing edges, but using parallel splines instead of separately routed
\r
52 * <p>Supports arbitrary RGB(A) colors in format #xxxxxx, where
\r
53 * each x is a hex digit. Supports also color names in x11 color chart.</p>

67 * Color used to fill the background of a node or cluster assuming style=filled. If fillcolor is not defined, color is used. (For clusters, if color is not defined, bgcolor is used.) If this is not defined, the default is used, except for shape=point or when the output format is MIF, which use black by default. Note that a cluster inherits the root graph's attributes if defined. Thus, if the root graph has defined a fillcolor, this will override a color or bgcolor attribute set for the cluster.
