This is from page 87 of a [document](http://home.earthlink.net/~username_2/fll/fll_programming_101_ev3_on_nxt.pdf) showing how to run NXT bricks using EV3-G software.

It uses the light sensor, not color sensor. You'll want to set the mode of the color sensor.

Inside a loop that will stop following a line if the left button on the brick is pressed.

Basically, the steering value of the motors is taken from the light sensor reading.
