You need many skills and talents to become a successful tattooer but two of the most important are technical application and artistic style. The first thing you learn in a tattoo apprenticeship is how to apply a tattoo with clean lines, even shading and saturated color that will stand the tests of time. Once you've nailed application, you can move on to artistry—which is what sets apart the innovators from the pack. Artistry encompasses color harmony, design aesthetic and overall creativity—causing distracted minds to stop their Instagram scrolling and take a pause to admire the work.

And while we enjoy beautiful and imaginative tattoos every day, we're busting out the best of the best for World Creativity and Innovation Day. This international holiday was established by the United Nations to help solve global problems and it's observed on April 21st. Although tattooing can't solve problems like world hunger or climate change, it can brighten our days during hard times and encourage others to support independent artists from around the world. Take a look at some of the most creative and innovative tattoos from artists around the world in the gallery below, then let us know your thoughts on this story on social media.
