Good morning Google Plus one users, we have decided that it was best for us to change the colors on your website. We know everyone likes washed out red, so this is the new color we added to your website:
The good news is it still functions the same, although I personally do not like washed out red on my website. Well you have no choice as Google does not allow you to alter their button in anyway.
I would imagine that Google is trying to be more like Facebook, and pattern their button along the lines of that of Facebook.
