Mac – Solarized background colour off in emacs under tmux

Exhibit I: plain Emacs.

Plain Emacs.

Exhibit II: Emacs under tmux.

Emacs under tmux.

The shades of colours are different, and importantly, the background colour differentiation is nil (e.g. look at the top menu). Anyone run into this?

I'm running tmux as tmux -2, $TERM in tmux is screen-256color, I'm using color-theme-solarized dark in Emacs, and Solarized for iTerm2 … a bit baffled!

I was having the same issue in Vim. Using the following in my ~/.tmux.conf worked for me after creating a new tmux session:

set -g default-terminal "screen-256color"

Mac – How to change the background colour of a single emacs buffer

I've created a emacs lisp package for this: https://github.com/vic/color-theme-buffer-local it uses Emacs' Face remapping to install theme faces locally.


(require 'color-theme-buffer-local)
(add-hook 'java-mode-hook (lambda nil (color-theme-buffer-local 'color-theme-robin-hood (current-buffer)) ))

Mac – Permanently override background colour of Emacs theme

The color-theme-billw function internally uses the color-theme-install-frame-params function to change frame parameters. So you can change frame parameters in the same way as follows:

(require 'color-theme)
(color-theme-initialize)
(color-theme-billw)
(color-theme-install-frame-params
  '((background-color . "gray12")))

C-hfcolor-theme-install-frame-params

(color-theme-install-frame-params PARAMS)

Change frame parameters using alist PARAMETERS.

If color-theme-is-global is non-nil, all frames are modified using modify-frame-parameters and the PARAMETERS are prepended to default-frame-alist. The value of initial-frame-alist is not modified. If color-theme-is-global is nil, only the selected frame is modified. If color-theme-is-cumulative is nil, the frame parameters are restored from color-theme-original-frame-alist.

If the current frame parameters have a parameter minibuffer with value only, then the frame parameters are not installed, since this indicates a dedicated minibuffer frame.
