Barchart Segment Label Colors

[mphillips]

Hello,

Is it possible to set the color of segment labels for the bars in a stacked bar chart? I have added the JSON below to my theme, but it only seems to apply to total labels, not the segment ones:

barChart: {
  label: {
    name: {
      color: '@myColor'
    },
    value: {
      color: '@myColor'
    }
  }
}

I would actually like to use different colors depending on the bar colors. In the picture below, the bar colors are from a custom palette. Is there a way to make the segment label black on the green bar, but white on the navy bar?
