Two particles with entangled photons

Silver jewelry inspired by the Nobel Prize 2022 in Physics. The Nobel Prize was awarded to A. Aspect, J. Clauser and A. Zeilinger “for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science”. The two particles do not have a definite state before they are measured. Both particles are gray, with no secret information, until someone looks at one of them. Chance decides . One may turn out to be green/blue. Immediately the other particle then gets the opposite color.
