adw-colors VS AdwCustomizer

You can also change the minimize and maximize icons to look like macos by copying the button related css that you can obtain from here into your gtk.css

Check this: adw-colors

You can either manually configure XDG_CONFIG_HOMe/gtk3.0 && gtk4.0 check this

You may check this one here. It will let you customize the Libadwaita stylesheet.

You can modify the named colours, there are some examples here: https://github.com/lassekongo83/adw-colors

More info here: https://github.com/lassekongo83/adw-colors/blob/main/HOWTO.md

After you have that, follow this guide to change the entirety of gtk to that accent colour. (including libadwaita) https://github.com/lassekongo83/adw-colors/blob/main/HOWTO.md

After in-team Round 1, we selected those names and we want GNOME community to select a name for our app

OK, I opened a new discussion for it and also joined the matrix room.

Install AdwCustomizer. Choose your color scheme and apply it (some applications may require you to log out first).

I think recoloring (color overrides defined by the user) is also important, which adwaita supports internally, but GNOME doesn't have this functionality exposed, you have to use AdwCustomizer. https://github.com/ArtyIF/AdwCustomizer
