Budgie Gender ?

[WallyBirdie]

I just got a little budgie and was wondering about the sex.
Male or female?
I know you genuinely judge by the color of the cere. But I'm new to this!
Is my deadly Piper a boy or girl? I was told he/she is around 4 months and has not had a first molt yet (still had little button eyes and barring on the forehead).

This is where I got my information/confusion.

Also, any idea how I can find out variety type?

Girl. Pink cere

I was always told pink was a girl and blue was a boy. But I have no first hand experience.

That is my understanding as well.
