Looks like to are using the theme package cyberpunk ( https://github.com/n3mo/cyberpunk-theme.el ) which is compatible with load-theme. I got confused because you used the phrase "color theme".

Contrary to what the install instructions say in that theme package's README page, one should not set the `custom-theme-load-path` variable WHEN you install the package using the emacs package manager (package.el) and initialize the packages using `package-initialize`.

If you have set that variable using Customize, erase it using the Customize interface.

Daniel,

What version of emacs are you on?

color-theme is a very old style of setting themes. I believe load-theme will not work for color themes.

Unfortunately it doesn’t. It has the same effect as without the „t nil“, background color is not applied.
