The "Ask Question" button now has a red border, red text and changes its background color to red when hovered over.
I find this a little irritating because I associate red buttons with actions I should be thinking over twice before executing them because they may have dangerous effects (which asking a question is not, in my opinion).
Is this on purpose so users think twice before they click this button? Or is there an other reason for the color change? I somehow liked the old black better and would like to know the reason for the change.
