Before you guys jump to conclusions about Neo's eye color changing being an error, you should probably read the Trivia section of her wikia. This it what it says:

During the episode "No Brakes", it was shown that Neo could change the color of her eyes at will, altering between pink and brown when staring at Yang, seemingly as a mocking gesture. They can also turn white (completing the ice cream theme) although rarely; one turns white as she removes the sword from her umbrella, and both turn white when the mysterious woman in red appears.
