Fifty-three contemporary artists worked with RxArt to create images created exclusively for distribution by RxArt. The RxArt Coloring Book is a softcover volume with 112 black and white pages designed for coloring. The cover depicts Ai Weiwei's colorful sunflower seeds from his Unilever Series, as well as a page of Weiwei's work transformed into adhesive stickers. The fourth edition of The RxArt Coloring Book was generously designed by Matt Murphy Design and underwritten by Warby Parker.
