Jay-Z's "Blue" Reference: He teamed up with GMC to release a limited-edition Yukon Denali painted a special shade of blue.
The Year: 2007
How It Showed His Love For His Favorite Color: Jay's not a businessman; he's a business, man! And he proved it by taking his "Jay-Z blue" line and turning it into a partnership with GMC that resulted in a Denali that was painted "Jay-Z blue." Pretty incredible.
