Google uses a playful multi-color palette to reflect its identity as a diverse, approachable, and innovative technology company.
Google's four-color logo was designed to be deliberately rule-breaking — using primary colors with one secondary green — to show that Google doesn't follow the rules. The palette signals inclusivity and playfulness while remaining immediately recognizable. Each color also maps to a product state: blue for links, green for success, red for errors, and yellow for caution.
