Eight is the character color with clear layers. The color of the characters is achieved by the shades and smoothness of the ink. The thick one makes it irritable, the light one moistens it. I think that adjusting ink is the basic condition for forming the shade of ink, and using ink is an important means to create a smooth artistic level. Therefore, adjusting the ink color well only meets the basic requirements of calligraphy works. How to use ink to take risks and harmonize at this level? Using moistening to extract beauty creates an artistic three-dimensional vision. This is a practical test of the calligrapher's technique of using ink. To produce this effect, you must use your brain to control ink. My experience is that after writing about six or seven words with one dip in ink, the ink on the pen will change from thick to light, then from light to astringent, or even dry. At this time, dip in ink again and continue writing, and the timing of dipping in ink for each line Naturally staggered, there will be changes in the ink color levels, forming an artistic sublimation from flat straight writing to three-dimensional dynamic.
