How to remove color from zsh ls?

I met some problems when configure zsh with oh-my-zsh on MAC OSX.

When I type 'ls -l' command, some of the output is blue. I don't know where it's from. I didn't set anything like this:

colors in ls -l output

I guess is it from $CLICOLOR, when I 'echo $CLICOLOR' ,it returns 1. While I didn't find where to modify it.

And by the way, how to customize the color of ls output when using zsh? I tried environment variable like $LSCOLORS in ~/.zshrc which does not work.

Playing with zsh is quiet different from bash and I'm new to zsh. Hope somebody can help me with that. Thanks a lot.

Solution

Problem is solved, but I still want to tell some difference between CLICOLOR and 'ls -G' after I tried them many times.

The problem I presented could be raised by both 'CLICOLOR' and 'ls -G' on MAC. If

export CLICOLOR = 1

is added to ~/.bashrc or ~/.zshrc, it means you allowed to use

export LSCOLOR = 'blabla'

to define the colors of ls command. This is independent to 'ls -G', which can also highlight 'ls' output but you cannot customize the color of it. (perhaps there is a not known way you can).

So try both when you meet this problem.
