Google: A Rebel?
Development of the Google logo was driven by the founders Sergey Brin and Larry Page, according to Ruth Kedar who designed the logo. They had a vision of a timeless design, simple and legible.
Yamaguma's take: "The primary colors add to the simplicity, and so [the logo] can be played with. Thus it has become one of the most successful brand identities. Instead of a chromatic progression, though, the L was made with a secondary color. This brings back the idea that Google doesn't follow the rules."
