Based on the theme of “遊戯 vs. 杏子 (ハンドレッド)”, I have created a color palette that reflects the contrasting personalities and styles of the characters involved. The palette includes vibrant and bold colors to represent the intensity of their rivalry, as well as softer hues to capture the subtleties of their individual traits.
