Custom themes for dojox charting

You could use the following CSS which will override the inline style for you chart (SVG) elements.

The selector says, select child x of a decedent of an svg group and change its fill color.

g > path:nth-of-type(1){
  fill: #FAEBD7;
}

g > path:nth-of-type(2){
  fill: #8A2BE2;
}

g > path:nth-of-type(3){
  fill: #7FFF00;
}

I would suggest to assign IDs to you charts so you can have full control on where and how applying your styles. Example:

 #yourChart > path:nth-of-type(1){
      fill: #FAEBD7;
    }

 #yourChart > path:nth-of-type(2){
      fill: #8A2BE2;
 }

 #yourChart > path:nth-of-type(3){
      fill: #7FFF00;
 }
