Shaving arms and dark hair?!? Myth??

I have super hairy arms for a girl and hate that about them. I want to shave my arms and have at one point, but I thought I seen my hair growing in darker than my usual light blond color. I’m not sure if it was the lighting or my mind being persuaded by the “myth” of shaved hair grows back darker in color. I’ve heard it both a myth and true, so if anyone has any experience with this or know if it’s a myth or not please let me know.
