Manga Artists' Copic Marker Colouring Techniques is a compilation style guide with tutorials in manga style and with specific combinations and palettes for copic markers. Originally published in Japanese in 2016, this English language translation is due out 25th June 2021 from Zakka Workshop. It's 146 pages and will be available in paperback format.
This is a very basic beginner accessible book. The introductory sections begin with the numbering system and different pens in the Copic range and understanding how to lay down color and correct mistakes. There's a short tutorial on other tools and supplies which the beginning artist will find useful (more advanced readers will probably not find much unknown info here).
Following chapters contain step-by-step tutorials showing skin, hair, eyes, and other features as well as clothing and accessories, backgrounds, flowers and nature and composition. There's a useful troubleshooting chapter which contains a number of good fixes for unevenness, removing/covering misplaced color, lighting, and different paper choices for varied effects.
The appendices include marker FAQs and colors, links and resources for supplies, and a short thumbnail gallery of backgrounds for use in drawings. Each of the sections contain some digital resources for transferring and enhancing manually drawn pictures into digital media and enhancements and other uses for artworks such as promotional materials, keychains, cards, and buttons.
This is not a drawing manual, the tutorials are aimed at blending and using the different types of copic markers to color line drawings.
