How a file is displayed in applications other than XL will depend on the
applications.

If you customize the colors in the workbook, then those colors will be
displayed when the workbook is opened in XL, regardless of how the file
is distributed.

I've been reading the forums and I've read conflicting responses. One
said you can't email your custom colors, another disagreed. Which is

show up in emailed versions of file?
