Create a vibrant image of a birthday celebration. In the scene, have a beautifully decorated cake with lit candles on a festive table, surrounded by colorful confetti and balloons. Capture the joyful atmosphere with people smiling and laughing in the background, their faces glowing with happiness. The setting should be warm and inviting, filled with bright, cheerful colors like yellow, pink, and blue. The image should evoke a sense of celebration and well-wishing, with a focus on the cake, candles, and the surrounding joyful ambiance.
