For my fam, the colors have triggered a family tradition. We name the trains based on the color- Mickey is red, Tink is light green, Donald is blue, Dumbo is grey, Dopey's purples, Cindy is light blue. Goofy is green, Minnie is pink, Aurora is coral, Yellow is Pluto, Gold is Pooh and black is Cap't Hook. This has been repeated on each trip since '99. The Kids hope to ride on their Favorite.
