# chart.colorCount

In styled mode, this sets how many colors the class names should rotate between. With ten colors, series (or points) are given class names like `highcharts-color-0`, `highcharts-color-1` [...] `highcharts-color-9`. The equivalent in non-styled mode is to set colors using the colors setting.
