I am using the phpdocx library to create pie chart diagrams in a .docx file. The (only) respective part I found regarding the color scheme is
<mc:AlternateContent xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">
<mc:Choice xmlns:c14="http://schemas.microsoft.com/office/drawing/2007/8/2/chart" Requires="c14">
<c14:style val="102"/>
</mc:Choice>
<mc:Fallback>
<c:style val="2"/>
</mc:Fallback>
</mc:AlternateContent>
Is there any primary source where the implication of these settings are documented and/or am I able to define them on my own?
Thanks and best!
