preview on ctrl + alt + del (finally nailed it):

On Windows 10 looks splendid even on my (Eizo) MVA screen.
It also exposes how excessively bright is the so-called "dark" mode.
I rather have pitch black backgrounds and clearly defined text, than that tiresome gray..

Added the Violet Black variant to show how to change default Blue accent

Updated to take care of logon screen not being pure black on 11
(due to acrylic being applied even if using solid color)

To better showcase it, no-lockscreen and no-image-lockscreen are used (with separate undo reg provided)

final update of the day - removed borders

Works beautifully. Thank you man.

Update to emphasize focused window on taskbar (with accent color) - this is more relevant in windows 10.

Added "Salmon Red Not" variant ;)
Added the original Pitch Black solid variant (with gray accent instead of blue)

Wow. I am so grateful for this! Incredible stuff. I should spam this gist on those .exe youtube videos and see how fast they ban me from commenting :)

so cool, can i restore the defualt theme if i need?

just run y_reset_accent_color_variables.reg
you can also save your current theme in settings and then re-apply it (or one of the default ones)

Thanks for the Black Theme. Works like a charm on my OLED Laptop screen, and helps to save battery. Default windows "dark", are not real dark.

loving this theme so far! you mentioned "removed borders" in one of the updates, but the borders look the same to me :\ is there a way to remove the annoying 1px border that is around all windows on 11? ss for reference:

Love the theme, great work. I was wondering if the folders could be black like the start menu? Thanks in advance !
