It's not even from your memory, it's from someone else's memory (it can only target opponents).
Digging into someones mind and beating them with their own magic is about the most blue thing you can do.
Framed the way it is, flavorwise, yes, it's blue.
Give the card a different flavor, though, and it could become red. Imagine a situation of inspired friendship, two men at a bar drinking and one of them says too much because they've had too much to drink.
This is the kind of stuff they should be doing in Red.
