This is my emacs file http://pastie.org/1003551. I want the theme to change when I am in shell-mode. But what happens is that the theme gets applied on all the frames. I set the variable color-theme-is-global to nil, but still the same problem is persisting.

(add-hook 'shell-mode-hook 'color-theme-monokai-terminal)
(set-variable 'color-theme-is-global nil)

These are lines 81 and 83 in my .emacs file. What should I do to make it work?
