colorscheme

A color scheme namespace: the context for interpreting color names

type: string, default: ""

In particular, if a color value has form "xxx" or "//xxx", then the color xxx will be evaluated according to the current color scheme. If no color scheme is set, the standard X11 naming is used.

For example, if colorscheme=oranges9 (from Brewer color schemes), then color=7 is interpreted as color="/oranges9/7", the 7th color in the oranges9 colorscheme.

  node [colorscheme=oranges9] # Apply colorscheme to all nodes

  4 [color=4]
  5 [color=5]
  6 [color=6]
  7 [color=7]
  8 [color=8]
  9 [color=9]
}
