highchart Axis values color - highcharts

Question

I could not find the color value for each Axis in highcharts api documentation.
in other words I mean changing color of numbers at left/down side of each axis.
currently the configuration for Axis is like this:
xAxis: {
lineColor: '#d8efe3',
labels: {
formatter: function() {
return this.value; // clean, unformatted number for year
}
}
},
yAxis: {
lineColor: '#d8efe3',
gridLineColor: '#d8efe3',
title: {
text: null
},
labels: {
formatter: function() {
return this.value / 1000 +'k';
}
}
},
edit:
there is nothing special about the chart, anyway assume the chart is as simple as this one:

Answer 1

I believe you are referring to the labels. Just change the style for the yAxis label.
DEMO
xAxis: {
lineColor: '#d8efe3',
labels: {
formatter: function() {
return this.value; // clean, unformatted number for year
}
}
},
yAxis: {
labels: {
style: {
color: 'orange'
},
formatter: function() {
return this.value / 1000 +'k';
}
},
lineColor: '#d8efe3',
gridLineColor: '#d8efe3',
title: {
text: null
}
},
Hope this helps and let me know if you have any questions!

Answer 2

This should change x and y axis label colors to red. I believe this is what you are looking for.
xAxis: {
lineColor: '#d8efe3',
labels: {
style: {
color: 'red'
},
formatter: function() {
return this.value; // clean, unformatted number for year
}
}
}
},
yAxis: {
lineColor: '#d8efe3',
gridLineColor: '#d8efe3',
title: {
text: null
},
labels: {
style: {
color: 'red'
},
formatter: function() {
return this.value / 1000 +'k';
}
}
},
