Imagine instead of Green and Red, it could be either Green or Red, or Blue or Yellow. If you measure it's Red/Green-ness, one will be red, and the other will be green. If you measure it's Blue/Yellow-ness, one will be blue and the other will be yellow. You can't measure the blue/yellow-ness of one and the red/green-ness of the other. As soon as one is measured, the other collapses into a particular color.
