LSCOLORS

export CLICOLOR=1

export LSCOLORS=GxFxCxDxBxegedabagaced


Explanation: 

CLICOLOR=1 simply enables coloring of your terminal. 

LSCOLORS=... specifies how to color specific items. 

Sequence of uppercase and lowercase letters specifies colors 
of the foreground and background items. 

Here is excerpt from man ls that explains meaning of the attributes: 


The color designators are as follows: 

a black 
b red 
c green 
d brown 
e blue 
f magenta 
g cyan 
h light grey 
A bold black, usually shows up as dark grey 
B bold red 
C bold green 
D bold brown, usually shows up as yellow 
E bold blue 
F bold magenta 
G bold cyan 
H bold light grey; looks like bright white 
x default foreground or background 

Note that the above are standard ANSI colors. The actual 
display may differ depending on the color capabilities of 
the terminal in use. 

The order of the attributes are as follows: 

1. directory 
2. symbolic link 
3. socket 
4. pipe 
5. executable 
6. block special 
7. character special 
8. executable with setuid bit set 
9. executable with setgid bit set 
10. directory writable to others, with sticky bit 
11. directory writable to others, without sticky 
bit 

The default is "exfxcxdxbxegedabagacad", i.e. blue fore- 
ground and default background for regular directories, 
black foreground and red background for setuid executa- 
bles, etc. 


The biggest change in readability of the colored text came from switching to use cyan (g/G) 
where that hard to see blue was used by default. 
ANSII blue has a very bad differentiation on Mac's homebrew, so changing to cyan made a huge
