It's light purple like Hagoromo's. The link to the volume cover you just gave, click on the picture in the infobox and zoom in on Sasuke's left eye. It is light purple like Madara's. Kishi colors (or at least, has input on) the volume covers. It is purple. The red Rinnegan you saw on Sasuke was not colored by Kishi.
