Take the 2-minute tour ×  I searched everywhere and mostly
people suggest the following code for setting a default color
theme:  (require 'color-theme)  However, this doesn't work. When
I start emacs I get this error:  Warning (initialization): An
error occurred while loading `/home/epsilonvector/.emacs':
Symbol's function definition is void: color-theme-name   This
happens for every theme name, even ones whose correctness I'm
sure of.  What am I missing?  share|improve this question  2

theme-initialize) in between the require and the call to the
theme name.  share|improve this answer This just rescued me from
a lot of frustration. Thanks! –  j4w7 Jan 24 at 13:54  First,
color-theme is a package that you have to install; I don't
believe it's included in any version of emacs. The download link
is here.  Second, you're not supposed to literally use the
symbol color-theme-name, but rather the name of the color
scheme: color-theme-hober, for example.
