On a pure and bright yellow wall, a small balcony with a black iron railing protrudes from the center outwards. Behind the balcony is a deep blue glass door, and in front of the door, a dark-colored chair is faintly visible. The strong sunlight clearly casts the shadows of the balcony and railing onto the wall, forming geometric dark yellow shadows. The image adopts a minimalist composition, with large areas of bright yellow contrasting sharply with partial deep blue and black, presenting a clean and refined architectural aesthetic and a rhythm of light and shadow.
