What's the best way to create a rainbow path and give weights to verticies

[Jeffrey C. Jacobs]

I'm trying to create a path where each link is a different color and where some vertices are visibly bigger.  Specifically, I want to encode metadata along the path with a color from green to red using the 511 colors from 00FF00 to FF0000 through FFFF00.  I also want to encode a weight logarithmically such that a vertex with less than 10 will be invisible, 10 to 100 more visible and 100,000 is pretty big but not huge; I think that's the maximum size the vertices would be.

What's the best KML description to accomplish this type of segmented path of varying color?

Yes, I want to use it in Google Maps, but right now honestly, let me get the grammar down straight and then I'll post in the google maps forum.

I think the only way would be to create each 'segment' of the line as a seperate <Placemark>. 

A <LineStyle> will apply to the whole placemark, cant style just parts of it. 

can use a <styleUrl> to create a common style and then reference it in multiple actual <Placemark>s
