The G+1 Button color scheme is changing to white and red shortly. Looking flagged in red color?? or better than old (blue colored) button?
I prefer the red one, 'cause it looks more deceiving to press. Haha. What I mean is, the color red is very attractive, so it's like a strategy of Google for people to notice their button.
Google is actually becoming more design councious now. The new button actually looks better than before. Tumbs up to google.
