Question: I am using 'zsh'. In some directory, when I do 'ls --color=tty'. I see some directories have
'blue text' with 'green background', which makes them hard to read.

Can you please tell me how to configure this?

Answer: 
The following works for me in zsh 5.7.1 (x86\_64-apple-darwin19.0)).

These lines in my .zshrc without any additional incantations configure the colours for ls:

```bsh
export CLICOLOR=1
export LSCOLORS=ExGxBxDxCxEgEdxbxgxcxd
alias ll="ls -alG"

```

For the configuration options you can use in LSCOLORS you can simply run `man ls` and find the section for LSCOLORS. CLICOLOR is explained there as well.
If you want to disable the blue color and restore the default white color, just uncomment the line "DISABLE\_LS\_COLORS =" true "in your .zshrc file
