LSCOLORS

The value of this variable describes what color to use for which attribute when colors are enabled with CLICOLOR. This string is a concatenation of pairs of the format fb, where f is the foreground color and b is the background color.

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 foreground and default background for regular directories, black foreground and red background for setuid executables, etc.

LS_COLORS

LS_COLORS='di=1:fi=0:ln=31:pi=5:so=5:bd=5:cd=5:or=31'

The parameters for LS_COLORS (di, fi, ln, pi, etc) refer to different file types:

di 	Directory
fi 	File
ln 	Symbolic Link
pi 	Fifo file
so 	Socket file
bd 	Block (buffered) special file
cd 	Character (unbuffered) special file
or 	Symbolic Link pointing to a non-existent file (orphan)
mi 	Non-existent file pointed to by a symbolic link (visible when you type ls -l)
ex 	File which is executable (ie. has 'x' set in permissions).

Color Codes

Through trial and error I worked out the color codes for LS_COLORS to be:

0 =	Default Colour
1 =	Bold
4 =	Underlined
5 =	Flashing Text
7 =	Reverse Field
31 =	Red
32 =	Green
33 =	Orange
34 =	Blue
35 =	Purple
36 =	Cyan
37 =	Grey
40 =	Black Background
41 =	Red Background
42 =	Green Background
43 =	Orange Background
44 =	Blue Background
45 =	Purple Background
46 =	Cyan Background
47 =	Grey Background
90 =	Dark Grey
91 =	Light Red
92 =	Light Green
93 =	Yellow
94 =	Light Blue
95 =	Light Purple
96 =	Turquoise
100 =	Dark Grey Background
101 =	Light Red Background
102 =	Light Green Background
103 =	Yellow Background
104 =	Light Blue Background
105 =	Light Purple Background
106 =	Turquoise Background

These codes can also be combined with one another:

di=5;34;43
