Multiple colors AND multiple data sets

[libardo]

I'm looking for a way to combine multiple data sets with my own array of colors.

An idea is to check for the presence of an array of arrays in chartColors:

chartColors: [
    ["2196F3", "2196F3", "2196F3", "2196F3"],
    ["CCCCCC", "CCCCCC"", "CCCCCC"", "CCCCCC"],
]

When i change bar colors manually via Powerpoint the color is appears in /c:barChart/c:ser/c:spPr/a:solidFill/a:srgbClr

Would a pull request be accepted or could we sponsor the maintainer to implement this feature?

I also want same feature as the attached image.
Is there any way to accomplish this?
