Dye from paper cake cases

[dippydaydream]

Hi I am currently icing 30 fairy cakes for my sons school fundraiser and noticed that the pretty paper cases that are various bright colours have leaked the dye slightly onto the cakes. The icing will cover this but do you think this will be ok? The paper cases are from Sainsburys?

I'm sure they'll be fine, it sometimes happens when the batter mix has been a bit too wet, it just wicks the dye up a bit, but it really is only a minuscule amount and its all food safe stuff anyways.
Hope they're super yummy and go down well.
