Here's a breakdown of what the colors are often associated with:
Blue: Often represents trust, reliability, professionalism, and security. In Google's context, it signifies their commitment to being a dependable source of information.
Red: Symbolizes passion, energy, excitement, and urgency. It reflects Google's innovative spirit and its drive to push technological boundaries.
Yellow: Evokes happiness, optimism, creativity, and warmth. It highlights Google's creative approach to problem-solving and its mission to make knowledge accessible.
Green: Represents balance, growth, harmony, and innovation. It's often seen as breaking the typical primary color sequence, signifying Google's "don't follow the rules" mentality.
The designer of the original logo, Ruth Kedar, famously stated, "We ended up with the primary colors, but instead of having the pattern go in order, we put a secondary color on the L, which brought back the idea that Google doesn't follow the rules." This emphasizes that the unexpected placement of green is a deliberate choice to show Google's unique and non-traditional approach.
Beyond individual symbolism, the overall multi-colored approach communicates Google's vibrancy, diversity, and the vast amount of information and services it offers.
