This is the best I can do with the default Microsoft theming engine, if you don't like something, it is likely because of those limitations.
This is built upon their High Contrast theme, so be aware that some programs might look different. If you don't like it just select the Windows default theme and everything will be reverted.
If you don't trust a zip download (it only has 700 byte and I am a nice guy) you can just create your own theme file and copy this text I created into it.
Install this theme.
Make all websites Dark with Dark Reader extension (set a hotkey to toggle on/off for sites).

I use this extension to make the scroll bars dark.

This program reduces the color temperature of you monitor at night, blue/white light can cause headaches, stress and bad sleep.
Download f.lux and set it to a value comfortable to you, I personally use 3200K.
If you like this theme please favorite/share it and leave a comment! Makes my work worth it!
Maybe consider being the first to donate a small amount, this post/theme/lists take time to create and I don't host on AdSpammed/FileHosting/malware sites like most other people!
If you share or post this theme anywhere, please add a Link to this original site! Be fair!
Have fun on the dark side!
Glad you enjoy the theme. I think I have made it quite clear in the description, that Microsoft decided it was a good idea to use the "TextColor" variable for those borders. So your only option is to make the text darker, which in my opinion is not a good idea. But feel free to edit your *.theme file to test different values.
