# How can I change the style of every newly opened notebook?

I'd like to make Mathematica open a new notebook using the Natural Color template (under the Creative category) by default. Is that possible? If so, how?

You can set the "DefaultStyleDefinitions" option in the Options Inspector. –  rm -rf Oct 9 '12 at 3:38
I set the "DefaultStyleDefinitions" (under Global Options->File Locations) so that, instead of "Default.nb" it pointed to "NaturalColor.nb" and I get some crazy worksheet (army green background, pink input boxes). I'd attach a screenshot, but I don't know how (first posting to stackexchange). I think that there are things inherited from Default.nb that are not present in NaturalColor.nb. –  glwhart Oct 9 '12 at 3:51
I don't remember, but you might have to point it to "Creative/NaturalColor.nb" –  rm -rf Oct 9 '12 at 4:04
YES! Thanks so much. That did the trick! (I'm not sure why but I'm happy just to have it work for now.) –  glwhart Oct 9 '12 at 4:11
Please check the answers to a related question to see if they work for you. –  kguler Oct 9 '12 at 4:12

1. Open up the Options Inspector (Format menu)
2. Select Global Preferences in the first pull-down menu
3. Search for "DefaultStyle..."
4. When "DefaultStyleDefinitions" appears under the Global Options/File Locations, click on the wrench/hammer icon
5. Select "NaturalColor.nb" in the "Creative" folder in the StyleSheets folder.

(For reasons I don't understand, you cannot directly navigate to Global Options/File Locations/Default... If you do, the wrench/hammer icon is grayed out. But if you search, it is clickable.)

Thanks @rm -rf for your help

On my installation, the path to the stylesheet you want (make sure "Creative" is in your path, there is more than one "NaturalColor.nb") is: /Applications/Mathematica.app//SystemFiles/FrontEnd/StyleSheets/Creative/Natural‌​Color.nb –  glwhart Nov 28 '12 at 1:36
