I think that the 100 values is going to be an issue no matter what.
For a smaller number of values (up to 32) you can create the chart in the Explorer and automatically assign persistent colors for each category value. The color assignments seem to persist when you export the exploration to a report.
In the Explorer, you set the color assignments by right-clicking a category in the Data panel and then selecting "Colors..."
A window appears that enables you to assign the colors for each value, but you can just click Assign remaining to persist the default assignments for all of the values.
I'm not sure if that is very helpful for you, but I thought I would share it. It may be that there is a way to do this directly within Designer (aside from individually setting display rules for each value) but I don't know it.
