Watercolor Vector Photoshop Action
You can use this action in photoshop CS6, CC, CC2014, CC2015, CC2015.5, and CC2017. The only restriction is that you must install the version in English. For now, other languages are not supported.
If you use a different language on your Photoshop, there is an easy way to switch to English. Check the video tutorial to change photoshop’s language to learn how.
