New color plugin doesn't color custom extended controller for pie, doughnut and polar #10850
Description
Feature Proposal
In version 4 (I'm testing alpha 3), there is new colors plugin which should set a default colors for dataset. PR 10764.
Currently the plugin is testing the chart type to get the colorizer but, creating own chart, extending existing controllers (and only in this case), the plugin doesn't recognize the type and use the default colorizer. This is often correct but if you extend a pie, doughnut or polar (where there is a specific colorizer) it doesn't color the data element.

Not sure if this is working as design. If yes, I'd suggest to add a note in the documentation.
Possible Implementation
Maybe the solution could be to test the controller class (instanceof ?) for each dataset meta with Pie, Doughnut or Polar controller class.
