List of Donald Duck universe characters
Like the nephews, April, May & June usually wear the colors red, blue and green, but unlike them, a color assignment has never been established. The girls also frequently wear yellow, purple and orange. However, one might consider "blue" to be April's color since that was the color she wore when she appeared solo in "Dell Giant" #35. It is also unknown which nephew is paired with which niece when they double date with their Uncle Donald and Aunt Daisy.
