=( what happened to them!!!

They were red, and today I pulled them off the clothes hoist and they have yellow stains all over them! I thought bleach?? but the stains are darker yellow on the outside - like rings, and then less yellow in the middle. does this sound like bleach - like the red has gone, or something else yellow has stained them?
do you think if i just wash them again it will be ok?

I only ever use washing powder... but DH has got napisan that he uses sometimes for his work clothes. they wouldnt have been in the same cycle, but if they were washed in the next cycle is there a chance they would have got stuff on them from out of the machine??

TIA!
