What shade of green is this?

Maybe this will help.

Kelly green?

I’d go with Kelly green too.

The tin and the cardboard container are two different members of the green family; I prefer the tin’s darker, more forest, hunter or pine green than the package. Kelly is very flamboyant for a dress. Granny Smith apple is a little more subdued.

I’d say “emerald”. Many fabrics are available in jewel tones.

Bear in mind that color varies a lot from computer to computer. When I put the same image up on two screens right next to each other, the colors almost never look the same. For instance, what looks like a real blue-blue on one can look almost turquoise on another.
