Specifies the default color when the pen color is specified with "default" when using AddPen. You can set any number of colors.

For example, if you specify 16 default colors as shown below, the following colors will be used for pens 1 to 16, and from pen 17 onwards the first color will be used again.

When 16 colors are specified as default colors

SetPenDefaultColor(c("#00FF00","#FFFFFF","#FFFF00","00FFFF#",
                     "#FF7F00","#FF0000","#FF00FF","#3300FF",
                     "#00BB00","#BBBBBB","#BBBB00","00BBBB#",
                     "#BB7F00","#BB0000","#BB00BB","#3300BB"));

If you do not configure anything, the following eight colors will be set.

"#00FF00","#FFFFFF","#FFFF00","00FFFF#","#FF7F00","#FF0000","#FF00FF","#3300FF"
