Similar to the principles of an ideal world, specific elements can enhance  reality.

Earth is a highly debated realm, where, after millions of years of evolution, various life forms struggle for existence by preying on one another. The world's aggression and imperfections create ample opportunities for improvement in human society. Individuals are significantly shaped by their surroundings, including their living environment, city design, and color schemes, highlighting the disharmony often seen in some modern megacities.

One significant aspect that can affect mood is color. The color yellow, in particular, is notably prevalent in nature—think of chickens, gold, and flowers, all recognizable to many. The sun's warm hues, the oranges of sunset and sunrise, the golden waves of wheat, and cheerful yellow chicks evoke positive feelings; this endless list underscores the uplifting essence of yellow.

These elements resonate positively with the human psyche.

The central idea of this series of works aims to integrate yellow into our lives, cities, clothing, and daily routines. By using yellow to influence our surroundings and boost our moods, we can collectively reduce aggression and foster a better world. Essentially, the notion is that an increase in yellow leads to a decrease in aggression. A brighter, more harmonious world is synonymous with the color yellow.
