Daniel, I reread your answer. 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. Then `(load-theme 'cyberpunk t nil)` will work. Check out the below emacs.SE for more detail. http://emacs.stackexchange.com/a/2113/115 -- Kaushal Modi On Jul 9, 2015 6:23 AM, "Kaushal" wrote: > Daniel, > > What version of emacs are you on? > > color-theme is a very old style of setting themes.
