How does Monica Sone use imagery in Nisei Daughter?

Imagery:

“Up to that moment, I had never thought of Father and Mother as Japanese. True, they had almond eyes and they spoke Japanese to us, but I never felt that it was strange. It was like one person’s being red-haired and another black.”

“Shod in spanking white tabis—Japanese stockings—and scarlet cork-soled slippers, the young women stood in tense excitement at the rails of the ship.”
