[Highcharts Pie Chart](#)
The following example demonstrates a monochrome pie chart.
We have already learned the basic configuration syntax of Highcharts in the previous chapters. Next, let's look at other configurations.

## Configuration
### colors Configuration
Use the `Highcharts.getOptions().plotOptions.pie.colors` property to configure the color of each pie slice.
```javascript
// Set monochrome and default theme for all pies
Highcharts.getOptions().plotOptions.pie.colors = (function () {
var colors = [];
var base = Highcharts.getOptions().colors;
var i;
for (i = 0; i < 10; i += 1) {
// Start with a dark color and end with a bright color
colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get());
}
return colors;
}());
### Example
Filename: `highcharts_pie_monochrome.htm`
$(document).ready(function() {
var chart = {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
};
var title = {
text: 'Browser market shares at a specific website, 2014'
};
var tooltip = {
pointFormat: '{series.name}: {point.percentage:.1f}%'
};
var plotOptions = {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '{point.name}%: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
};
var series= [{
type: 'pie',
name: 'Browser share',
data: [
['Firefox', 45.0],
['IE', 26.8],
{
name: 'Chrome',
y: 12.8,
sliced: true,
selected: true
},
['Safari', 8.5],
['Opera', 6.2],
['Others', 0.7]
]
}];
// Make monochrome colors and set them as default for all pies
Highcharts.getOptions().plotOptions.pie.colors = (function () {
var colors = [];
var base = Highcharts.getOptions().colors;
var i;
for (i = 0; i < 10; i += 1) {
// Start out with a darkened base color (negative brighten), and end
// up with a much brighter color
colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get());
}
return colors;
}());
var json = {};
json.chart = chart;
json.title = title;
json.tooltip = tooltip;
json.series = series;
json.plotOptions = plotOptions;
$('#container').highcharts(json);
});
