​A person is greatly influenced by their environment and the place where they live. The city, its infrastructure, shape, and color scheme all play a crucial role in shaping our perceptions. Notably, there is a disharmony in the shape and color schemes found in some modern megacities.One significant factor that can influence mood is color. For instance, the color yellow is prevalent in nature—found in chickens, gold, and various flowers. This color resonates with many familiar images: the sun, the warm hues of sunsets and sunrises, the golden tones of wheat, and birds like yellow chicks. These objects, including sunflowers and amber-colored honey, evoke positive feelings in the human mind.The concept and main idea of this series of works is to promote the introduction of yellow into our urban environments, clothing, and daily lives. Yellow is proposed as a method to positively influence a person's surroundings and mood, and to impact society as a whole. The premise is simple: an increase in yellow can lead to a decrease in aggression, potentially leading to a more harmonious planet.
