# series.gantt.dataLabels.backgroundColor

The background color or gradient for the data label. In addition to regular colors, there are two special setting for this option:

- `auto` will set the background color the point's color.
- `contrast` will set it to a contrast against the text color, with an opacity allowing to see the underlying content. The contrast is great enough to ensure readability for the text according to accessibility standards.
