The Google Play Books logo features a book-shaped icon with a green bookmark inside it. The green color used in the bookmark is the same shade of green used in the Google Play logo, which helps to create a visual connection between the two platforms. The book-shaped icon represents the primary function of the platform, which is to provide users with access to a vast library of digital books.
The use of negative space in the Google Play Books logo is also noteworthy. The inside of the book-shaped icon is left empty, which creates a sense of openness and possibility. This reflects the idea that the Google Play Books platform provides users with endless opportunities to discover new books and authors.
The typography used in the Google Play Books logo is also carefully chosen. The word "Play" is written in the same font as the Google Play logo, which helps to create consistency across Google's various platforms. The word "Books" is written in a bold sans-serif font, which gives it a sense of solidity and strength.
Overall, the design of the Google Play Books logo is a simple and effective combination of symbols, colors, and typography. The book-shaped icon and green bookmark create a strong visual identity for the platform, while the use of negative space and bold typography convey its values of openness, diversity, and strength.
