How to Turn on the Black Theme in Microsoft Office

  • MORE

Microsoft has rolled out a new theme for Office that's easier on your eyes and also makes buttons and other menu items in the Ribbon stand out. If you thought the Dark Gray theme wasn't dark enough, here's how to enable the higher contrast, Black theme.

The Black theme is available now for Office 2016 and Office 365 users. The other Office themes--Colorful, Dark Gray, and Classic White--are still there.

    I don't see black anymore and I do have o365. I loved my black theme, really... it was fantastic and a beautiful change to a mostly unchanged platform. Whenever I change the registry key to 4, it just reverts back. I have black as an option on my work laptop (no registry tweaking) so i don't understand why its not working on my other PC with the same o365 account.

  • Nick S. Says:

    You now have to subscribe to O365 and pay monthly/yearly, to have the black theme activated.

    The registry modification does work, but isn't persistent. Another DWORD value will re-create itself upon app closure, called "pendingUI". The value would be a number besides "4", which is the Black theme.

    Say goodbye to Black theme when you install Visio ! :(

    Tried in Office 2013 with no luck. Any suggestions or registry hacks for using a black/dark theme in 2013?

    "Blinded by the white/light-gray/dark-gray stock themes" Thx!

    The registry is usually found typing "regedit.exe" in start menu.

  • N Taylor Says:

    I can't find the registry. No matter what I try to search it says "Window cannot find"...

    Is there a trick to finding the registry on Windows?

  • Bliss Says:

    Thanks Steve, you're a life saver. It worked for me.

  • B Hurd Says:

    I've been looking for the solution to enable the black theme if it isn't listed in the themes. Thanks Steve!!

    For anybody who had the black theme removed, use regedit to set key per Steve's comment:
    Set "UI Theme" value to 4. Located here:
    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\UI Theme

  • Grateful Jones Says:

    Thanks to you steve, I have black theme back! Awesome.

  • Steve Says:

    FYI: set value to 4
    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\UI Theme
