Colorful Novels on a White Bookshelf — Postcard

Two neat white shelves hold a rainbow of book spines — navy, teal, orange, red, green — arranged with the kind of order only a dedicated reader keeps. No single title stands out; the color and rhythm of the row is the whole picture.

Slide it into a letter for a friend who just finished reorganizing their own shelves by color.
