I'm looking for a good strategy to create, in InDesign ideally, type on a path with colour blocks behind it, set in a series of concentric circles.
I have not used type on a path tool previously so had planned to use paragraph rules above/below, offset, to put the colour behind the type: I didn't know that this tool does not work with type on a path: uh oh. And, I've discovered, neither does the underline tool work effectively with type on a path: double uh oh. As a former typesetter, I've set a lot of horizontal type and not a lot else: not a graphic designer, but I was talked into building this thing and now I'm stuck.
The source file [handed over to me] is a complete nightmare, so not a great starting point given the amount of time that I have: I spoke to the person who did make it and they suggested I would be better off starting fresh.
I hope that someone can offer me a strategy that will be fairly quick to execute/adjust/set up. You can see from this image how the colour blocks behind the type don't form a full circle: they don't need to fade at the edges like this, but I need a way to control where they start and end, independent from the type that sits above each colour block/part of the circle. I had hoped that I could do this with type controls, and not do any drawing.
