If any of the names in the above table appear rather unreadable due to
their color, try clicking on 'Select All' in the 'Edit' menu of the browser.

• A custom color is specified by

  colorentry index: red value  green value  blue value

• Color values are arrays [0, ..., 255] of integer

• Examples

  colorentry 35: 210 218 255  // alice blue
  colorentry 42: 205  92  92  // indian red
  colorentry 78:  46 139  87  // sea green

graph: { color: lightyellow

         colorentry 32: 0 0 128

node: {title: "aiSee"  shape: trapeze  color: lightblue  bordercolor: blue}

node: {title: " GDL "  shape:rparallelogram linestyle:dotted color:16 bordercolor:1}

node: {title: "AbsInt" shape: circle  color: darkred  textcolor: 0  bordercolor: red}


edge: {source: "AbsInt"  target: "aiSee"  color: 32}

edge: {source: "AbsInt"  target: " GDL "  color: 32  linestyle: dotted}

       }

• A custom color must be specified before it can be used:

  graph: {
     node: {title:"Sense of Life" color:42}  // this won't work
     colorentry 42: 42 42 42
         }
  

• If multiple specifications compete, the last one applies:

  graph: {
     colorentry 42: 255   0   0   // 42 = red
     node: {title:"??" color:42}  // the node is blue
     colorentry 42:   0 255   0   // 42 = green
     colorentry 42:   0   0 255   // 42 = blue
     node: {title:"!!" color:42}  // the node is blue
         }
  

• The default colors can be overwritten:

  graph: {
     node: { title:"oops" color: red } // the node is blue
     colorentry 02:   0   0 255        // red = blue
     colorentry 01: 174 218 255        // blue = my favorite blue
     node: { title:"uups" color: red } // the node is blue
     node: { title:"I hate these ugly default colors" color: blue}
                                       // the node is my favorite blue
         }
  

• ASCII control characters can be used

  in order to influence the text color of a node,
  an edge label or an information window

• aiSee supports the following alternative notations:

  darkgray  // instead of darkgrey
  lightgray // instead of lightgrey
