You need at very good microscope and a sensitive camera. But you can also just look at the color from many molecules in solution. In both cases the light emitted will change from red to green when you add the keys to open the box.

The researchers attached fluorescent molecules to the rim and to the lid. But this gets technical, and I'm not an expect on "fluorescence resonance energy transfer." My apologies to the experts if I get this wrong. As I understand it, when the two fluorescent molecules were close to each other (when the lid was shut), the efficient energy transfer causes a red fluorescence signal. When it opened and the two molecules were further apart, the less efficient energy transfer produced a green signal. But it's not like petri dishes were flashing with green and red lights. To see the signals, researchers used spectroscopy to measure the wavelengths (and hence the colors) of light emitted. The reference to “red and green dye” was a little unclear, you’re right.
