The panel's appearance is controlled by your theme's SVGs. You will have to modify them to get the panel to change color. To make it easier, there is the Breeze AlphaBlack theme, which offers readymade command-line tools to change its panel color and transparency: https://github.com/Zren/breeze-alphablack.

Breeze AlphaBlack (https://store.kde.org/p/1084931/) automatically installs a widget which can modify the theme to change the tasks.svg move the line to the edge of the screen.

Have you looked into breeze-alphablack.

My best alternative so far has been using Lightly to remove the details that I find unnecessary in Breeze such as borders on almost every element. I also use Breeze AlphaBlack to be able to easily change the taskbar colors.

I use pywall basically to update the system colors and use Breeze Alphablack to change the theme colors dynamically.

Some themes like Breeze AlphaBlack have easily-configurable colours and transparency.

One example for me personally is that I like to use this custom Plasma theme, Adagio, and it isn’t available in the KDE Store nor any repos AFAIK. So I have to place the files manually in /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/, which requires root. A Linux veteran could easily do it with the terminal but someone like me who’s tech savvy but unfamiliar with the terminal would have a significantly easier time doing it in a GUI.

Plasma Theme: Adagio (Windows 10-esque lockscreen. Make sure to turn off "Confirm logout" in the KDE settings or the system glitches out.)
