When did color bombers come out of Fortnite?

I have a bet with a friend, he said season 1 color bombers came out and I say no. I have been playing since season 1 and can't remember that it came out in season 1.

It came in season 3 or 2

under no circumstances 1

15 December 2017

Color bomber skin is a rare Fortnite outfit from the set Sunshine And Rainbows. This character was released on December 15, 2017 at Fortnite Battle Royale, and the last time she was available was 7 days ago.

So season 2
