Change the "Proof Generation Successful" Icon

[#1]

The current "Proof Generation Successful" icon causes confusion for our users. They want to be able to quickly tell what documents/versions have a proof built on them.

The green box with a check mark is too similar to the style of the proof status SOCD acronym. People assume that it has something to do with the proof status itself.
It would be nice if it was a different color than green as well– as our user's have come to associate that with a completed proof status.

Can this be changed to something that is a little more unique?

Here's just a suggestion. I want to hear what others recommend!
Thanks all!

I like this idea. An alternative would be to actually show SOCD here, as it appears elsewhere.
