Park Ri-no's fourth book, following "Friendly Drawing," "Friendly Coloring," and "Dynamic Drawing," is "Friendly Light and Color." [Light] is expressed as [color] through [material].
It is not about coloring in a way that makes it look pretty, but rather about understanding light and materials and expressing them with color when drawing.
In other words, this is a book that presents a method of ‘drawing’ ‘realistic’ ‘light’ and ‘color’ through the author’s experience and know-how.
