Can't Change Chart Data Label Text Color

I attempted to use the highcharts method to attempt to set the color, essentially:

$.extend(true, chartObj.plotOptions,{ 
    bar: {
        dataLabels: { 
            enabled: true, 
            style:{
                color: “white”
            }
        } 
    } 
})

And it appears to set the CSS style on the text of the data label as white. Of course, the browser plows over this and implements the .sk-chart-standard .highcharts-data-labels tspan style in the skuidtheme.css applied on the parented div over the highcharts style.
