white onion turned my lentils red

[DairyNips]

Confused, I usually make lentil soup with freshly chopped onion and carrots and lentils.
Last night I got some bags of ready chopped white onion reduced so I used them today in my soup.
Some of them went a bit red when I sautéed them but I thought nothing of it.
Now I've gone back to stir it and the red lentils (which are usually orange) are dark red?!!
Has anyone had this? Is it safe to eat?

Bump

Anyone?

I have no idea, how strange. Does it still taste nice? If so I'd still eat it

It smells ok.. Haven't tried it, scared it'll make me sick!

Why would you think they'll make you sick? If the onions are OK, and the Lentils are OK, what is the problem? I would imagine that they are a slightly different type of Onion and it has a different sugar level, or something.

You can dye clothes with onion skin(rust colour). Was there a rouge piece of skin in it?

You wont be sick with onion.

There was no skin in it. It was white onion, pre chopped.. Never did eat it in the end as it was such a strange colour..
