On Teacher's Day, Xiao Bai, Xiao Huang, Xiao Lan, and Xiao Zi met with flowers of different colors on the campus. Xiao Bai looked at the flowers in everyone's hands and thought for a while, and was happy to announce what she found. Rules: (1) The colors of the four flowers are exactly the same as their four surnames, but the color of the flowers in each hand is not the same as their last name; (2) If the flowers in her hands are exchanged with Xiao Huang, or Little Blue swaps, or swaps the flowers in Xiao Lan's hands with Xiao Zi, then the color of the flowers in each hand is still different from their last name. Based on the above statement, it can be inferred that the colors of the flowers in the first hands of Xiaobai, Xiaohuang, Xiaolan, and Xiaozi were? ['Purple, blue, yellow, white.', 'white, yellow, blue, purple.', 'yellow, white, purple, blue.', 'blue, purple, white, yellow.']
