Kool-ade Pickles as seen in the N.Y. Times. Has anyone sucessfully done this. If so how? The receipe is nogood

The pictures they show are pickles comletely colored bright red or green. Stop and think. How can you take a dark green object drop it in red food dye and expect it to turn all bright red as seen in the pictures. Two packs kool-ade, one pound sugar doesn't work. Neither does adding 1/2 brine. So are they fake photos or is there a way to do it?
