2) What is the color sensor comparing values to?

3) How does the color sensor know what is 0 or 100% reflected light intensity?

4) What environmental factors on the robot, attachments or in the room, could be affecting light?

Try using “on for seconds” mode instead of rotations or degrees in move steering block. I think misbehavior is caused by the occasional malfunction of motor rotation sensor.
