彩 means 'to color'

Nature abounds in these essays, including blood-red sunsets, brightly colored birds, and fall foliage. Logically, art forms such as painting, calligraphy, and lacquering also emerge as central themes. But who would have guessed that color ties in with many body parts: blood, the eye, lips, skin, cells, and even a point where energy is concentrated. Mental states also matter here with faces flushed with rage, diligence in work, depression and lifelessness, and vitality. Moreover, multiple essays touch on religion, minerals (including one ingested for longevity), and old forms of currency (one of which was chocolate!).

This bundle is a masterclass in the artistic mindset. Essay 1290 celebrates vibrant colors, whether for painting with watercolors or oil or for designing spaces. Essay 1388 explores traditional craftsmanship, particularly highlighting the beauty of Japanese carpentry and the rigors of apprenticing for ages to master a skill. Essay 1590 covers several fields, from carving wood, making sculptures, and engraving metal to creating traditional tattoos that form a complete picture over much of the body. Essay 2065 extols the virtues of extreme detail, especially in doing elaborate drawings that bring dreamworlds to life with extraordinary realism.
