I decided to have a stab at creating my own Dark theme to match my Windows 10 Dark Mode. Not perfect, but thought I'd share in case anyone else would like it. Probably missed a few settings, so feel free to let me know, or play with it yourself.
(Yes, as you can tell from the screenshot, I use an ultrawide monitor, hence the layout of the window!)
Great theme! One issue in mine, which I see is not an issue in your screenshot. The very top line, title bar where you also find the windows buttons for minimize, maximize and the X for close, on my installation this one is still light. In your screenshot I see that title bar is also dark. Yes, my Windows 10 is set to dark theme with dark accent colours and all that. Where do I change the global colour of the title bar?
I think I know what you mean. If it was like me, it's the inactive title bar colour that you're seeing, not the active one, which you can change in Windows Settings.
In the link in my post there's a blog post about how to change the inactive window title bar. It's a bit of a roundabout way of doing things, as the setting in Windows changes the active title bar, then you have to go into the registry to copy the value across to a new setting.
The blog post is from the Winaero tweaker app site, which (as I later found out!) actually does this easily for you (under 'Appearance / Inactive Title Bars Color') which might be easier!
Take a look and see if that's what you're experiencing.
Oh, and thanks to you both for the compliments on the theme. Not done this before and in my hour of procrastination just kept messing with it!
FYI, the Windows title bar colours I used where:
Active Title Bar: #1C1E21
Inactive Title Bar: #373E43
I set my active to : ff767676
and inactive to : ff484a4c
Which is a dark grey inactive and a medium grey for active.
For those who wants to make a custom inactive color as well, this is where you find the registry DWORD: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
Just follow the link to the guide in the OP.
Further to Leo's answer, I've set the colour to (70, 70, 70). I thought the theme would pick this setting up, unless I did something wrong when I exported it?
Dark theme looks great, but I can't get the breadcrumb path and the nav arrows to the left of it to change to the darker background. I'm using 12.10. Any suggestions appreciated! Great job!
Thanks Leo. That works but I do miss having my virtual folders displayed. Also am I correct that theme colors being applied to things like the Preferences page and the bottom status bar of the picture viewer aren't supported at this time? Or am I just missing another setting somewhere?
