There are many ways to use Photoshop to color lineart. This tutorial demonstrates the method I use. It was created using Photoshop CS2 for PC. Newer versions may need slightly different steps. It also assumes that you are somewhat familiar with the software. :)
Coloring art in a program like Photoshop is not only fun (because you can get very creative using the tools and filters) but it can also save you time and materials, since you don’t have to worry about dry markers, broken pencils, or possibly starting over because of a mistake! You can also recolor the same image many times to see how different color combinations look.
Although following the tutorial exactly will help you replicate the same effect that I created, the best way to learn is to experiment and create your own results!
Before moving to this stage, I prepared my lineart using the steps outlined in my Digital Inking tutorial.
