I noticed that by whatever her surroundings are, her eye color will nearly match that color. Her eyes are usually naturally a grayish-green color, but that seems when her brunnett colored hair is casting a shadow over her eyes. I've seen scenes on High School USA DVD version where Nancy's eyes were at first Greenish-Blue, then her next scene, when the light hit her eye, coupled with her hair color and the guy in front of her, her eyes were either a mix of green and dark gray, gray-green, or greenish-gray. Then on the scene where she was working in the bakery, her eyes went from a blue-green 50/50 ratio to an 80/20 ratio on the blue-green color spectrum, meaning 80% blue and only 20% green on her irises. I call this a Vanessa Williams type blue. Thats the color it was at on my T.V. And yes, with a multimedia setting on your T.V. set, her eyes would look even bluer. On the scene where she was at the school dance with Michael J Fox, her eyes were a shiny gray color. I also notice that in well lit rooms, her irises will shrink so small, smaller than most other people's irises, that it looks like the size of a small pinpoint. That phenomenon I noticed was on a scene from The Wrong Woman. I only seen that same phenomenon on Vanessa William's eyes, Fairuza Balk's eyes, and an unknown man on the street's eyes who was wearing nothing but a white buseness suit. We all know that Nancy McKeon wears a variety of different colors everyday. And also I seen that one pre-division pic of her, and her eyes were a bright lime-green color. But, she was also wearing something colorful as well. Vanessa Williams eyes change colors based on her surrounding. Could Nancy McKeon's eyes do the same things as well? It seems that when Nancy also walks even a few feet down a room, her eyes will either change shades on the color that it is or change colors completely, just by walking down a hallway.
