             * For supported color formats, see the
             * [docs article about colors](https://www.highcharts.com/docs/chart-design-and-style/colors).
             *
             * A scalar color axis is represented by a gradient. The colors either
             * range between the [minColor](#colorAxis.minColor) and the
             * [maxColor](#colorAxis.maxColor), or for more fine grained control the
             * colors can be defined in [stops](#colorAxis.stops). Often times, the
             * color axis needs to be adjusted to get the right color spread for the
             * data. In addition to stops, consider using a logarithmic
             * [axis type](#colorAxis.type), or setting [min](#colorAxis.min) and
             * [max](#colorAxis.max) to avoid the colors being determined by
             * outliers.
             *
             * When [dataClasses](#colorAxis.dataClasses) are used, the ranges are
             * subdivided into separate classes like categories based on their
             * values. This can be used for ranges between two values, but also for
             * a true category. However, when your data is categorized, it may be as
             * convenient to add each category to a separate series.
             *
             * Color axis does not work with: `sankey`, `sunburst`, `dependencywheel`,
             * `networkgraph`, `wordcloud`, `venn`, `gauge` and `solidgauge` series
             * types.
             *
             * Since v7.2.0 `colorAxis` can also be an array of options objects.

             * See [the Axis object](/class-reference/Highcharts.Axis) for
