This is using @MaximBelov's fork, version 0.5.4. Custom *backgroundColor* on a pie chart's datasets are ignored, see https://jsfiddle.net/8erzf0hn/   It works (i.e. chart shows the expected custom colors) if you - switch to 2.9.4/0.4.0 (legacy code, image on the left); - do not import the colorschemes plugin - set the colors as a custom scheme (uncomment the *options*)
