Try:
    cp /etc/DIR_COLORS ~/.dir_colors

edit ~/.dir_colors and make your changes.
implement changes:
    eval `dircolors -b ~/.dir_colors`
test your changes:
    ls -l

Here's the changes I found most useful for green text on black background:
RESET 0 # reset to "normal" color
DIR 01;37       # directory
LINK 04;36              # symbolic link (If you set this to 'target' instead of a
                # numerical value, the color is as for the file pointed to.)
MULTIHARDLINK 00        # regular file with more than one link
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, or non-stat'able file
MISSING 01;05;37;41 # ... and the files they point to
SETUID 37;41    # file that is setuid (u+s)
SETGID 30;43    # file that is setgid (g+s)
CAPABILITY 30;41        # file with capability
STICKY_OTHER_WRITABLE 30;42 # dir that is sticky and other-writable (+t,o+w)
OTHER_WRITABLE 34;42 # dir that is other-writable (o+w) and not sticky
STICKY 37;44    # dir with the sticky bit set (+t) and not other-writable

# This is for files with execute permission:
EXEC 01;32

Links are underlined which is nice.

Hi,
I noticed that when I ssh into a CentOS 7 Host I get slightly darker
colors in the ls output compared to the local (gnome-terminal) bash.
Since I'm using a dark background the darker blue used for directories
for example on the remote host is harder to read then the slightly
brighter blue used on the local system.
Does anyone have an idea why the colors are different and how to change
that?
