How to change the theme of Office 2013

All those themes are awful, I've only had 2013 on my PC for about 10 minutes, but I'm already rolling back to 2010... I started getting a headache and watery eyes within about 60 seconds... and as I spend 90% of my day with Outlook, Word & Excel, there's no way I'm putting up with this...

Bring back the Darker themes and I'll upgrade, and deploy it to the network, until then, there's no way I'm subjecting the teachers & pupils to this torture.

Thank you for the feedback on Office’s new look. We are actively collecting, sorting and reading through feedback on Office 2013’s design and User Experience.

While we do not have any additional Themes planned at this time, it is an issue we are watching very closely.

Great!  When you stop watching and start doing let me know; until then 2013 goes in the same pile as ME, ME2 (Vista), and ME3 (8).  Lots of potential obliterated by some mind-numbingly silly design decisions.

Unfortunately, the theme options are quite horrible and there is no way, that I can see, to customize it. The "Dark" option isn't very dark at all. Really all that does is give less contrast between the text and the background making it even harder to read. I am defenitely glad I tested this before deploying it to 300 users. Honestly, I like the theme better on 2010 because it gave better contrast and easier to find things. The Folder Pane is more difficult to find the folders because of the poor color choices, in my opinion.
