This analogy is confusing because it is incorrect in some fundamental ways. You aren't just opening a box and seeing one or the other color. The measurement itself determines a role in the outcome that you couldn't predict in advance.

It is more like you get to choose to measure only one of the red, green or blue channels. If you send a message containing which channel and the measurement, the other person can do the same measurement and find the complementary value. Without the channel and the original measurement the other person just sees random behavior.

The spooky part is that I don't choose the color channel to measure until after the entangled balls are separated
