First off, this is my first feature request. I have not found a similar feature request so please bear with me if this is a duplicate or incorrect place to post it.
I have noticed that whenever posting questions on Stack Overflow the most views are coming when the question does not have answers yet. My guess is that this is due to that most (usually low rep users) want to have the best change of getting their answer accepted as the correct answer in order to get more reputation. But this means that whenever an answer is posted on a "normal" question, the likeliness of getting a better answer decreases rapidly for every "incorrect" answer made.
For instance: You post a question on how you could do "(4 + 4) / 2" and get "4" as result. The first answer by person A is "Why do (4 + 4) / 2 and not just 2 + 2".
When person B (with a potential much better answer) browses the list of questions this question is now switched from RED to GREEN/WHITE, thus when person B browses the list he doesn't notice the question as easy due to that his brain is (unconsciously?) set to answering RED questions. I think this might also have a psychological explanation due to the colors use (RED is more "attractive" to the brain then "GREEN/WHITE" I believe), but I don't know that for sure.
Of course one could argue that this is what voting is for, but this is not seen on the question list page and therefore irrelevant.
My suggestion for this would be to add a "not-accepted answer" functionality. This functionality can only be used when a question does not have an accepted answer. This "not-accepted" function should not give any negative reputation.
When an answer is made to a question, it should still change to GREEN/WHITE. BUT, when the questioner set the question to "not-accepted" it should change back to RED (still stating 1 answer is made).
When another answer is posted the question should again change to GREEN/WHITE, and so on. When one of the answers is chosen as the correct answer that answers the question, the other answers that have the status "not-accepted" should be reset. There is no use for showing an answer was not accepted when the correct answer is chosen.
