When I load the radspreadsheet from an excel file, the foreground color is not loaded.
A workaround is to use the Kendo Spreadsheet widget directly which imports fore color: https://demos.telerik.com/kendo-ui/spreadsheet/server-side-import-export
Repro steps
go to https://demos.telerik.com/aspnet-ajax/spreadsheet/examples/import-export/defaultcs.aspx
add some text with specific fore color
save the excel file
import the excel file
Expected: there is no change
Actual: the fore color is not imported. Also, font size changes, but see the related item for that
