Since the orange dialog are gone, we now have red dialog instead for (almost) everything (except the blue one I guess).
I was wondering why the dialog is red when we just perform a valid action? Why not a green dialog instead? I feel wrong when I see the red dialog, like "woops did I make something wrong?".
Color dialog that seems ok to me.
When I voted to reopen a question on one I already voted for:
When I try to upvote my own answer:
Color dialog that should wear a green color (or at least different than red)
When I vote to close a question. As a success message, I got a red dialog. Err.
I do not find a question / or an answer to flag, but I guess the message will still be red.
With previous orange dialog, I didn't find the color wrong because it doesn't match a wrong/right action as red does.
