The idea of this project for Malpaso book editorial was to design a sistem for a pocket book collection assigning colors to each genre, where the black is for no fiction, the white is for fiction and the yellow is for music.
Each book has a color on their front spine, and that color repeats also in the keywords of the cover.
It is possible to add more genres by adding a new color to the cover of the new genres and just follow the same system.
