They have the wrong photo in the directory. Blue with yellow cap is correct for II. I is reddish with a green top, and III (original) is dark with a red top (the newer version is all black, but I've read there's been several different bottles for III alone). III is still being produced, albeit reformulated. I think, but am not sure, that I is discontinued. Not sure about II as I still can find it pretty readily available online.
