This is an example of how to present a route in Sinatra that returns a colored version of an existing svg. This assumes the first line is the line, which is what inkscape produces. Just drop in any svg, and it will give you one where it is colored in with the given color.

/dynamic/foo.svg returns the normal image.

/dynamic/foo.svg?color=red gives you a red image.

/dynamic/foo.svg?hue=150&sat=50&light=50 gives you a slightly green version of the image.

/dynamic/foo.svg?hex=fff gives a white version of the image.
