Check this class: https://gist.github.com/2390007

    {
        if (static::is_windows())
        {
            return $text;
        }

        if ( ! array_key_exists($foreground, static::$foreground_colors))
        {
            throw new \FuelException('Invalid CLI foreground color: '.$foreground);
        }

        if ( $background !== null and ! array_key_exists($background, static::$background_colors))
        {
            throw new \FuelException('Invalid CLI background color: '.$background);
        }

        $string = "\033[".static::$foreground_colors[$foreground]."m";

        if ($background !== null)
        {
            $string .= "\033[".static::$background_colors[$background]."m";
        }

        $string .= $text."\033[0m";

        return $string;
    }

In all likelihood the command you are running is checking to see if output is to a terminal and not colorizing it if it isn't. There is usually a way to force it, but that's going to be specific to the command itself; in the case of git diff, you can specify --color=always.
