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 :D
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.
