Rainbow Brite experts?

[Sweet_Stuff]

Hi there,
I'm looking for any RB experts.. Did they make two varients of the '80s regular sized dolls?

My childhood Patty O' Green doll had blue designs on her shoes. I recently bought an '80s Patty who has plain two toned green shoes.. I'm wondering if the all green shoes version was the first..? I also have seen two different '80s Rainbow Brite dolls, each with different shoes.. Any input is appreciated!
