Got it. We finally got the name of the great green from Brenda: Fresh Melon Green # 21GY30-617. The problem then was that we were not sure what paint company it was.
"Fresh Melon" paint not only turned up that it was a Glidden paint, it also turned up a super cool project that Jason Gessner did with the color. He built himself a "green screen" like the blue kind they use in movies, and filmed his daughter driving her toy car in front of it. You have to check out the links.
(Thanks, Jason!) MGR
