ls assigned colors because it was configured to do so, either by you or your distribution. > plus, it's unusable in a script, because then "ls" suppresses the color. ls doesn't do anything different in a script, you probably just have an ls alias. Aliased are typically not sourced for non interactive shells

it depends on the invocation, and by default it checks for tty or not. the aliasing often does not touch this. example alias: $ alias ls ls='ls --color=tty' and from ls(1): "With --color=auto, ls emits color codes only when standard output is connected to a terminal. The LS_COLORS environment variable can change the settings. Use the dircolors command to set it." ("tty" and "if-tty" are the same as "auto")
