Trying to upgrade an old thermostat to nest, I have the following wires, yellow, white, red and blue.. in many videos he 4th wire is green.. I'm confused as to where this blue wire goes..

Are the terminals on the old thermostat not labelled? Usually you just have to match the old letters to the Nest letters.
