The blue, yellow and red (on fourth down) lines are added by computers that scan for certain colours (i.e. the green of the gridiron), then replace the necessary pixels with the required colour. The final image is then televised. Note that these lines are not visible on the field itself to spectators, coaches, etc., and there are sometimes difficulties with adding the colours (for example, snow or mud discolour the ground so the computer does not recognise it as such, or a uniform is almost the same colour as the ground). In these situations a technician can normally fill the gaps manually.
The yellow line that you see on your TV screen is not on the football field. It is only a visual reference for those of us watching the game on TV so we can see how far the offense needs to go to get a first down.
There is not really a yellowline on a football field. It is put on there by the tv station people to show where the first downs are. It is pretty close to impossible to keep dawing new yellow lines on the field while the game is going on
If you are talking about the line ofscrimmage or the First down line it is animated.
