The Secure Shell Chrome App combined with a remote Linux box, screen and emacs is a game-changer. Among other things, it turns my Chromebook into a programmer friendly hacking environment.
One quirk of this combination is that the color scheme emacs loaded by default was often illegible. I'd typically run M-x customize-themes to pick a better color scheme, but no matter the theme I selected the colors were always harsh and often left text hard to read.
Turns out, there's a quick fix to this issue. The problem and its fix is described here. It boils down to this: the Secure Shell App sets the terminal type to xterm-256color. Emacs supports this terminal type, granting it access to, well, 256 colors. But I'm running screen, and screen morphs that terminal type to screen.term-256color. Emacs doesn't know what to make of this terminal type so it falls back to to 8 color mode.
This becomes clear when I ran M-x list-colors-display.
The following tells emacs that screen's terminal type is one that it knows:
(add-to-list 'term-file-aliases
'("screen.xterm-256color" . "xterm-256color"))
I added this code to my init.el, restarted and suddenly got access to 256 colors.
Now the default emacs color choices make sense. Such a simple fix, and I didn't even realize I had this problem.
Your code is focused on web stuff, mine was purely terminal focused:
