Steps to replicate:

2. Add the Pie chart gadget to an existing dashboard , choose the above project and group by "Status".
   The Colours will repeat after 7th status. Please refer image.

Suggestion:

It would be good if there are more colours in the palette for Pie chart gadget so that the repetition is not easily evident. Or any other approach where in this repetition is not evident.
