The original Google Photos logo featured a pinwheel with four colored sections - red, green, blue, and yellow. This design was intended to represent the diversity of photos and memories that users could store and share on the platform.
In 2016, Google updated the logo to simplify the design, making the pinwheel all blue and removing the individual colored sections. The new logo still featured the pinwheel shape, but with a flatter and more modern look.
In 2019, Google made another update to the logo, introducing a new design that incorporated a multi-colored pinwheel. The new logo featured six sections - two shades of blue, green, yellow, orange, and red. This design was intended to reflect the vibrancy and variety of the photos and memories that users store on the platform.
The multi-colored pinwheel design also helped to differentiate Google Photos from other Google products, which tend to use a consistent color scheme of blue, red, yellow, and green.
Overall, the evolution of the Google Photos logo reflects the platform's focus on simplicity, diversity, and innovation. The original pinwheel design represented the diversity of photos and memories that users could store and share on the platform. The subsequent updates simplified the design and made it more modern, while the latest update introduced a new, colorful element that helps to differentiate the platform from other Google products.
