Dye Transferred in the Wash?

I put a mixed load of washing on and didn't realise that my new dark blue and red swimmers would leak on everything. I had 2 other loads of washing to put on and it was about to rain so when the first load was done I put it straight in the dryer without noticing anything. Later that day when I got the clothes out of the dryer I saw that my swimmers had turned my denim mustard yellow shorts to a blue/grey washy colour, as well as, my multicoloured pajamas shorts, everything else was fine though. Is there a way of getting the blue/grey wash out of my shorts?
