White versions of the Google logo are used during times of great tragedy. Instances when the white logo has been used include the Polish aircraft disaster which killed President Lech Kaczyński, the Qinghai earthquake and the Gansu mudslide of China. White logos would also appear if you customized the main page of Google by adding a background on the now-decommissioned iGoogle application. They also still appear if you customize the Google Chrome browser with themes that have backgrounds that the fully colored logo is not visible over.
The white version of the logo was introduced in May 31, 1999.
This icon still appears on some pages.
The icon first appeared in August 2012. This logo is basically an inverted version of the 2008 icon.
Following its logo change in 2015, the new Google icon now uses an uppercase "G" with the four colors from the new main logo. The rebrand also introduced the new "Google dots". The "G" favicon is also slightly reminiscent of the 1993 logo for Gymboree.
