The Coloring Book Tie is the perfect necktie for those who are either artistic or who don't take life too seriously. This fun tie is filled with pictures of coffee and donuts, pictures that you get to color in. You could always choose to leave the tie colorless, but that would sort of defeat the purpose of it.
Perhaps the only downside to the Coloring Book Tie is that washing it after it's been colored could be a bit tricky. It's also quite large, which means you'll need to clear out some time to complete the picture or risk stepping out with a half-colored tie. The tie itself is made out of linen and does not include markers. It costs $29.99 and is available in the ThinkGeek store.
