A bunch of colorful balloons are floating in the sky. The background is white and clear, with no other elements present except for these balloons. Each balloon has its own color, including reds, pinks, yellows, greens, blues, or purples. They appear to be tied together in the style of strings that lead up into the blue sky. This creates an atmosphere filled with joyous celebration as if celebrating something special. The overall effect should feel festive and happy.
