This work was done on F3 canvas with 36 colors made by Mont Mort. From monochromatic to mixed, the paint for this work is a very well-balanced material. Without this material, it would have been difficult to realize this work. Waves are another motif that I often paint, but it also has a meaning. There is a theory that in 4-dimensional space, you can go back and forth between the past and future just like going up and down a staircase. I think this idea is very interesting, and I describe the various waves as if they were time. This work is a wave with a distorted impression. The coloring is both ugly and beautiful. It may be an expression of my own way of thinking about time. I have always painted with 100% of the day's energy. However, I think there are times when a work from a less powerful day is appreciated. But I have never really wanted to go back in time. I am indifferent to time, but there is something about the past that I miss. Technically, I used a nylon brush for the first time in this work. The colors are not easily mixed in the brush, and the material's coloring remains on the canvas, which is true to the vivid yet dark style of this work. I frequently use different nylon brushes. I use a wide range of brushes, from wide to narrow, and since this is the first time I am using these paints, I experiment with them and put as many colors on the canvas as possible. Since all the materials were easy to dry and use, the work was not that difficult compared to the artwork itself.
