The polycarbonate panels feature vibrant gradient colors, including blue, pink, orange and yellow tones, creating a unique diffused light effect. The interior of the cube emits a soft, warm light, accentuating the translucency and design of the polycarbonate. The floor of the square is made of reflective tiles, amplifying the reflections of colors and light from the cube. In the background, historic European buildings with classic facades contrast with the modern cube design. A human figure walks nearby to add a human scale to the scene. The atmosphere is artistic and captivating, perfect for a modern architecture project combining innovative materials and urban aesthetics.
