Is this colourization made officially by Oda?
Yes. Oda does everything in One Piece. Literally everything. That's why he has no editors. Because he had infinite time.

being a sanji fan is suffering
No it's not. It's just absurd playing into some idiot games where anything Sanji can do is automatically diminished. I mean we're arguing about him using CoA when we know he can and B he uses CoO more often. No one argues about Zoro's CoO like this. No one argues about Zoro's speed. No one argues about Zoro sky walking. It's just absurd nonsense that people end up playing into without realising it's an absurd game.
As proof, you can see someone saying the anime proves that Sanji didn't use X in Y scene and then saying that the anime can't be used as proof for Sanji using Y in Z scene.
you can see people saying Sanji is strong and it's dismissed as them joking. The vivre card saying Sanji is a top-class fighter is ignored. But for Zoro, every whisper is taken as 100% fact.
There's no point, and Sanji beating king or queen or whomever won't change it. Just like how Yonji magically became the weakest Vinsmoke by several times, whoever Sanji beats will become the weakest calamity and called gifter level.
