Highcharts : Change opacity of a column chart

Use the rgba format to change the opacity.

Example:

color: 'rgba(255, 255, 255, 0.50)'

Reference

Highcharts Docs chart design and style

Semi-transparent colors in Highcharts are given in the rgba format rgba(255,255,255,1). The last parameter is the alpha or opacity that ranges from 0, fully transparent, to 1, fully opaque. Because of this, there are no separate opacity options in the Highcharts API.
