Example file made with Excel 2013
Custom colors of Data Points in Excel 2013 made charts are not preserved when the spreadsheet is saved as XLSX in LibreOffice Calc.
Steps to reproduce:
1. Create a new spreadsheet in Microsoft Excel 2013.
2. Create a simple chart (a column chart with default settings will do) with the default values.
3. Change the color of a Data Point.
4. Save the file as XLSX.
5. Open the file with LibreOffice Calc and save it with a different name as XLSX.
The data points revert to the default color.
The custom color of the data points should be preserved.
