How do I change the fairy style of the fairy box?

Try forge or anvil. I think it's similar like frog.

I tried it but it doesn't change.

That is so frustrating. I was farming the Fairy Box for hours because I wanted to have a specific style. Only to then read that it's appearance depends on the player ID. But I know for certain that I already had two different colors on my save file. Maybe my ID changed somehow.
I don't understand why this has to be a thing and why it can't just be like the Frog Egg.
