I am so glad about this topic!
I was having trouble with this as well. While I was seeing the difference in the input field, my brain sometimes just wasn’t quick enough to distinguish between the two. And I hadn’t noticed the color difference at all before this post.
But now that I see it, my last review session just went a lot smoother 
So thanks to the op for posting this! It changed my reviews and I hope you will get it sorted out as well
