In this case, the electron acceptor is the blue dye DCPIP. The dye is blue when oxidised and colourless when reduced, so it is possible to monitor the loss of blue colour as an indication that DCPIP has accepted electrons. the prior consent

"WebSep 15, 2024 · The Hill Reaction depends on electrons released during the light-dependent stage of photosynthesis being picked up by the blue electron acceptor DCPIP. The reaction can only occur if the thylakoid membranes are illuminated as the light-dependent stage stops in the dark. " - Hill reaction dcpip
