F3 and F8?

hey guys im not sure which color my dart falls under, but what is the difference between Dodge's:

"F3 Dark Green Metallic" and,
"F8 Dark Green Metallic" ??

anyone have any pics of either or? to compare?

I have both of these colors on my 69 Dart. F3 is called light green metalic. F8 Is dark green metalic. The Dark green is the common interior dash and metal parts of the door frame.
