Green and pink bitcoin amounts in blockchain.info wallet

[tripbeetle]

I notice that one of the transactions in my blockchain.info wallet shows the bitcoin amount on a pink (or sort of orangish?) rectangle, while all the others are on a green rectangle.
I've searched online as much as I can for an explanation, but can't find anything. Does anyone know what the different colors mean?
Thanks.

green=incoming transation
pink/red = out going transaction

you can tell because the amount of value inside the pink/red rectangle is a minus. and also the arrows are coloured to emphasize this
