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?
Regards, Dennis

You should have an environment variable of LS_COLORS. Check for differences or simply take the settings from the system you prefer and set it in the other system. Normally, you'd put that in your .bashrc if your using bash as your shell.

Type "env" to see your environment variables: one of them is LS_COLORS. I'm guessing they are different on the two machines.

Two approaches:
You have environment variables which say what colour codes to use with which filetypes. It would seem one system is merely using blue, the other using bright and blue (it's a two-part thing).
Depending on what your terminal is, if you're using a graphical one, you can change the palette used by each colour, and make your dark blue brighter.
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.

Thanks for the pointers everyone. There seems to be a subtle difference in what "dircolors" reports and what is present in the LS_COLORS env variable:
0 dennis@nexus ~ $ dircolors LS_COLORS='rs=0:di=01;34:ln=01;36:mh=00:.....
0 dennis@nexus ~ $ env|grep LS_COLORS LS_COLORS=rs=0:di=38;5;33:ln=38;5;51:mh=00:.....
Notice how the entries in the dircolors" output have only two values but the entries in the env variable three values associated with them.
Now I only need to figure out what exactly "di=01;34" vs. "di=38;5;33" means...

di = directories to be coloured thus 01 = bold or bright (depends on the terminal which one it does) 34 = blue
If the third one is a set of ANSI colour codes, then I'd say:
38 = an extra colour beyond the defaults, so you probably have something else that defines what that colour is 5 = flashing text 33 = brown (i.e. dark yellow), possibly this is a fallback option if the other colour doesn't work
Alternatively, is it a set of RGB colour codes? Like this:
38 = 38/256 of red 5 = 5/256 of green 22 = 33/256 of blue
But only an educated guess.
(I wrote fractions, as it's probably a red level of 38 out of a range of 0 to 255, darkest to brightest, respectively.)

Ah, now found a reference for the latter
38;5;33
The 38 prefix apparently means to set the foreground colour, but a 48 prefix apparently means to set the background colour.
No idea how they're using the 5.
The 33 is a colour, but I don't know how that's defined.
Apparently, it's to do with xterm, so you might look into that.

The "3" of 38 is setaf, the 8 is the first part of the color specification. This 3 number combo is used only on terminals capable of more than the standard 8, typically 256 colors.
I think the "5" seems to be constant, perhaps meaning a color beyond the std 8 and the 33 completes the color specification.

I found two good references one for the codes themselves and one for all the color codes: https://en.wikipedia.org/wiki/ANSI_escape_code http://misc.flogisoft.com/bash/tip_colors_and_formatting
38 sets the extended foreground color which can be followed by either: 5:n where n is the color index in a standard 256 color palette or 2;r;g;b to set rgb colors from a 24 bit palette.
