The first and second videos in the series focus on coloring the jellyfish with pencils. The third part is an optional video about doing the background. Peta describes a variety of techniques that we can use to create immersive backgrounds. She demonstrates one, in particular, that is both quick and easy to follow.
The one she shows in the video requires the use of soft pastels which aren't that expensive if you want to get a set. There's not much of a difference at what you can achieve with pencils or pastels other than the time and effort required. Pastels are quick and easy to apply. They give a really soft finish suitable for backgrounds such as the sky, a grassy meadow or underwater scenes.
Peta is an excellent teacher and she explains every little thing as she goes along. This means even an absolute beginner can achieve fantastic results with her tutorials, plus you learn a lot about coloring techniques that you can apply in other pictures as well.
Of course, the thing with tutorials is that you're not likely to find one for every image in every book that you want to color in your preferred medium. But you can certainly get better at coloring and use advanced techniques to create realistic or vibrant images.
Another thing that I like to do helps me with getting better is to save finished pictures by colorists that I find online. You can get a lot of ideas about new color combinations, background effects different media, and techniques which you can then apply to your own coloring.
For example, you can complete the pictures with a limited color palette - just two or three colors. Or you can color certain parts of the picture with black pens so that the parts which do have color stand out more. You can try playing with rainbow colors, shadows, night scenes, winter or snow scenes and so much more.
Now that I have completed this tutorial, I'm going to start a project that I've been meaning to do for quite a while - recording my colors for future reference in a journal. With more than 300 pencils (and counting!), I certainly need one. And what do you know? Peta has a video for that too! I'll put up a post on my results and a short how-to once I'm done.
