I may have found a second refrence! (I'm not sure because it's subtle)

[MJN SEIFER]

FF7

Cait Sith: Give In to relation ships you're lucky colour is BLUE!

FF9:

<Insert another pointless fourtune here> You're Lucky colour is <Insert colour here including blue>

Hmmmm?

[m4tt]

...What?

[Kawaii Ryûkishi]

He's talking about the fortune you can get in the Dali inn. No, it's not a reference; the concept of a "lucky color" is common.

The best references in the game come from nowhere when your least expecting it. Dont' try so hard to find them . Let them come to YOU

In the Legend of Zelda: Majora's mask, if you go into Miaku's loft in the Zora Village thingy, you can read his diary and his lucky color is green. I gotta agree with Kawaii Ryukishi.
