Lori that runs this channel has a goal of not only showing you how to color but teaching you how to color. From her vast range of videos you can learn all manner of techniques that you can apply to your coloring projects. As well as coloring, Lori often answers questions from subscribers and gives feedback on work (often providing demonstrations). Lori has spent a lot of time creating a color blending system that you can purchase. The system has a vast range of information including which colored pencils blend well together. You can check out the CMW system here.
