Its hard to say, just by looking at it, the coloration seems out of place...
If those colors are true to life I would think that it is contamination of some sort,
it would help to mention whether there is some sort of odour that you can discern from the jars, sometimes the smell is a better giveaway, and can let you know the contamination much before you see any physical signs of it...
