Just like last year, the year before and in fact every year since 2008, Google shows some special decorations when searching for [gay], [lgbt], [lesbian], [transgender], [queer] and other queries that include these words. It's the LGBT Pride Month and Google made the search navigation menu more colorful.
You can also check the colorful decorations from 2008, 2009, 2010, 2011, 2012 and 2013.
