What do the colors on the Google account logo mean?
I've noticed that the ring around my Gmail icon has four colors - blue, red, yellow, and green - that are not equally sized. I haven't noticed this anywhere else on Google, but I have a feeling the size of the segments are relative to usage. Am I using more "blue" type documents than "yellow"? Is it unequal for everyone, or does the size have meaning specific to the user account?
