YAxis labels and series color the same - highcharts

Question

I have a chart with two series. One series uses the left YAxis, the other uses the right YAxis. I would like the labels on each axis to have the same color as their respective series.
I know this can be done by manually assigning the colors, eg:
yAxis: [
{
labels: {
style: {
color: "red"
}
}
},
{
labels: {
style: {
color: "green"
}
}
}
],
series: [
{
color: "red",
yAxis: 0,
data: []
},
{
color: "green",
yAxis: 1,
data: []
}
]
But I would ideally prefer not to assign colors manually. When you don't specify any colors, the series colors are set automatically. I would like for the corresponding axis labels to have the same color.

To change the colors automatically, you can use the chart load event and update y-axes:
chart: {
events: {
load: function() {
this.series.forEach(function(s) {
s.yAxis.update({
labels: {
style: {
color: s.color
}
}
}, false);
});
this.redraw();
}
}
}
