Procreate, the Apple Design Award 2013 winner, is a powerful tool for drawing or painting original artwork and photos. Just like art programs you may use on a PC, there are a couple of ways to blend colors using Procreate on your iPad. The Smudge tool works much like a dry brush on a wet canvas and can be used to blend two or more colors into each other. The other method involves blending colors on different layers by adjusting their opacity levels, much like graphic design artists do on programs like Photoshop. With either method, it’s best to practice a few times on a new canvas before trying the techniques on a serious art project. Tips Warnings Writer Bio
