Nomura has expressed after designing serious and moody main characters for "Final Fantasy VII" and "Final Fantasy VIII", he wanted to give Tidus a cheerful attitude and appearance, which is reflected in the name Nojima chose for him ("Tiida" is the Okinawan word for "Sun"). Nomura has also mentioned a contrast between the lead male and female protagonists was established by Yuna's name meaning "night" in Okinawan. Since Tidus did not originate from Spira, his outfit was made stand out from the ones from world's inhabitants. Nomura also placed image colors to each main character to give hints regarding their personalities. Since both the player and the main character find themselves in a new world, Nojima wanted Tidus' understanding of the world to reflect the player's progress in the game; a connection that allowed the player to advance Tidus' first-person narration of most of "Final Fantasy X".
