I seem to recall saying something about this the other day... Glad that Dark Horse isn't the last to the coloring book race. Just kidding. I don't care. Oh, I will say that calling anything like this a "program" just sounds dorky. I say that as a dork too. From Dark Horse Comics:

Dark Horse proudly announces a brand-new adult coloring book program hitting bookshelves and coffee tables this fall.

Kicking off the coloring books line are Avatar: The Last Airbender and the fan-favorite Serenity series. Each adult coloring book features forty-five pages of original artwork created specifically to be colored on thick, heavyweight 10 x 10–inch pages at a $14.99 value price point!

Relive your favorite scenes from Avatar: The Last Airbender with this beautifully detailed coloring book. Filled with original black-and-white illustrations by artist Jed Henry and produced in collaboration with creators Michael Dante DiMartino and Bryan Konietzko, this book is sure to be a hit with the Avatar fanatic in your life.

The Serenity Adult Coloring Book is a must-have for fans of the ’verse. Join the crew of the Serenity on an adventure through the ’verse where you can relive your favorite moments from the Firefly series—and more. This stunning adult coloring book is filled with detailed and completely original black-and-white illustrations for you to color however you desire.

More adult coloring books will be announced in the months ahead, so stay tuned for your chance to color your favorite comic creations.
