Color Themes missing, not following Powerpoint File

[OriginalAustin]

Hello Everyone,
I'm an in-house designer and our team is attemping to put together a Powerpoint file with master slides in an attempt to get all of the sales and execs on the same page. Everything has been going pretty well until we try to create the Theme colors. For example, I have our custom Theme colors on the file on my computer, but when my fellow designer opens the file on her computer, the theme colors do not exist.



I'm wondering where I am going wrong on this one?

Thanks for any help!

Austin
