If you weren't aware, coloring books for adults are enjoying a bit of a renaissance—as they offer a playful framework for both creativity and anxiety/stress reduction. And brands, of course, are picking up on the trend. Go to Barnes & Noble and have a giant coloring session in its stores. Oreo is getting into the action with colorable packaging for the holidays—its inaugural foray into the e-commerce direct-to-consumer space.

Starting in mid-November, the "Wonderfilled" Mondelez brand will be offering "Colorfilled" Oreo packs for sale at a new Oreo site, shop.oreo.com. The packs will feature exclusive illustrated designs from artists @Jeremyville and @TimothyGoodman. You just color them in digitally—using a palette of colors as well as some bits of "seasonal flair." When you're done, the packs will be shipped to you. (They will cost $15 each.) If you're more of a traditional kind of colorer, you can also buy blank packs that come with markers so you can physically color them in at home. Other items for sale will include T-shirts featuring the artists' designs with fabric markers for coloring.
