# series.bubble.color

The main color of the series. In line type series it applies to the line and the point markers unless otherwise specified. In bar type series it applies to the bars unless a color is specified per point. The default value is pulled from the `options.colors` array.

In styled mode, the color can be defined by the colorIndex option. Also, the series color can be set with the `.highcharts-series`, `.highcharts-color-{n}`, `.highcharts-{type}-series` or `.highcharts-series-{n}` class, or individual classes given by the `className` option.

In maps, the series color is rarely used, as most choropleth maps use the color to denote the value of each point. The series color can however be used in a map with multiple series holding categorized data.
