I guess you read it wrong, the uke asked 《why the word youth (in japanese) is written with the character for blue, they could have used other colors》to that the seme replies that for him 《youth is gold》referring to the uke's blond hair, meaning that for him the other guy is his youth... I would say
Omg that’s so cute, I’m so jealous son singleLMAAO
What did they mean when he got youth in gold and the other guy got it in blue?
Maybe I'm just stupid but I deadass don't know
