How to change the theme of Office 2013

I must say that I am very disappointed with the new themes in Office 2013. Like most of you I work in the IT department and have a say in what we deploy to our 5k computers and I will be strongly suggesting we not upgrade to office 2013 until we have better options for the colors. I have been using it for a week and have been getting headaches from looking at the dark gray interface for 8 hrs a day (and the white and light gray are even worse). I love the product with all the new features and how well it meshes with Windows 8 but please give us some color options.

I just installed 2013 yesterday and the first thing I wondered was how can I change the theme.  White is too bright and the grays are depressing.  How difficult is color?  Everything else seems to be good so far - but I keep wanting to have a colored screen.  Microsoft we are only the people who take time to complain.  I would get that there are millions more like us who just wouldn't bother because Microsoft won't do anything about it anyway.  Step up and get us all color and contrast!

I'm replying to my own post because since posting my comment here, I returned my new Dell computer because of a mark on the touch screen that wouldn't come off. I got a similar Toshiba to replace it. When I installed Office Home & Student 2013 last night (3/18/13), EXACTLY the same way I had on the Dell on 2/24/13, it installed differently. There is now something called Office Backgrounds, which was not available on 2/24/13. You can have all sorts of things up in the title bar now, such as creatures under the sea, stars, stripes, food, and other "doodles". Although I don't use them, it inherently made that part of the screen and the edges darker. Even though there are still only the three color themes, the screen is much easier to see, especially on a high-glare surface like a touch screen.

So, either Office installs differently on different manufacturer's computers, or maybe they listened to us? It's not as much as we want, but at least it's a little better.

BTW, Office Backgrounds can be found by clicking on the main screen's menu line:  File, Options, General.

Either send me a refund for Office 2013, or send me a Copy of Office 2010. I want my Black color scheme back, NOW!
