There's a little about it at the bottom here http://www.ocr.org.uk/qualifications...y-a-h032-h432/
It seems it can be either purple or green, and comes down to the state that the ion is in?
At least that's my interpretation, but it's been 4-5 years since I did Chemistry and spent most of my lessons not paying enough attention!
