# Below are the color init strings for the basic file types. A color init
# string consists of one or more of the following numeric codes:
# Attribute codes:
# 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
# Text color codes:
# 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white
# Background color codes:
# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white
NORMAL 00   # global default, although everything should be something.
FILE 00     # normal file
DIR 01;36   # directory
LINK 01;33  # symbolic link.  (If you set this to 'target' instead of a
            # numerical value, the color is as for the file pointed to.)
FIFO 40;33  # pipe
SOCK 01;35  # socket
DOOR 01;35  # door
BLK 40;33;01    # block device driver
CHR 40;33;01    # character device driver
ORPHAN 40;31;01 # symlink to nonexistent file

# This is for files with execute permission:
EXEC 01;37;41

# List any file extensions like '.gz' or '.tar' that you would like ls
# to colorize below. Put the extension, a space, and the color init string.
# (and any comments you want to add after a '#')

# If you use DOS-style suffixes, you may want to uncomment the following:
