Detailed Description

Standard styling for rendering series in charts.

This class provides four standard palettes, each composed of eight different colors (these are recycled at index 8).

The three colored palettes are a variation on those defined at http://www.modernlifeisrubbish.co.uk/article/web-2.0-colour-palette.

The following table lists the background color, and font color of the different palettes:

Neutral	Bold	Muted	GrayScale
Gmail blue	Mozilla red	Ruby on Rails red	Gray #1
Shiny silver	Flock blue	Mozilla blue	Gray #2
Interactive action yellow	RSS orange	Etsy vermillion	Gray #3
Qoop mint	Techcrunch green	Digg blue	Gray #4
Digg blue	Flickr pink	43 Things gold	Gray #5
Shadows grey	Newsvine green	Writely olive	Gray #6
Magnolia Mag.nolia	Magnolia Mag.nolia	Last.fm crimson	Gray #7
RSS orange	Rollyo red	Basecamp green	Gray #8

The border pen is in all cases a gray pen of 0 width, while the stroke pen is a line of width 2 in the background color.
