Here are a few examples:
* Daphne Blake: While Daphne's hair color is often depicted as blonde, in some episodes and the "Scooby-Doo on Zombie Island" movie, her hair is drawn as a reddish-brown color.
* Velma Dinkley: Velma's hair color can also fluctuate, sometimes appearing more reddish-brown than her usual orangey-red.
* Several supporting characters: There have been many red-haired female characters who appear only in specific episodes, like villains, friends, or random townspeople.
It's important to remember: The coloring of the characters in Scooby-Doo has varied significantly throughout the years, so what's considered "red" can be subjective. However, there's no doubt that there are many red-haired ladies in the Scooby-Doo universe!
