Cannot set colors when using addSeriesColumn in multiColumn columnChart

[dominik-eller]

Describe the bug
There are only 5 default colors, that keep repeating when having more than 5 columns. I cannot change the colors of a multiColumn chart using ['color' => '#ff0000'] for example.

To Reproduce
Steps to reproduce the behavior:

1. Create a ColumnChartModel
2. Set multiColumn to true
3. Add one or more series to the chart
4. Try to set colors to the columns

Expected behavior
The defined colors are used for a multiColumn chart.

Screenshots

Additional context
The issue is about the columnChartModel when using multiColumn and adding series with the addSeriesColumn method.

Solution Ideas
Adding color as a parameter before extras array or allow colors to be set in the extras array.
