I've customized my Toolkit pie chart but now all slices are same color

I've implemented a resource dictionary so that I could customize my tooltip on a pie chart. But now the series returns a pie chart where the slices are all the same color. How do I get it to act like it did before I applied the resource dictionary? PieDataPoint.xaml is the file I copied into my project to use as a reesource dictionary.

I was able to solve my issue. Below is my resource dictionary. I had to manually define my colors as a style near the bottom.

<ResourceDictionary
