The dark background and the radiant golden tones indeed suggest a serene full-moon night, a significant theme in traditional Pichwai art. The shimmering elements, like the golden blossoms and the glowing ambiance around the peacocks, beautifully depict the moonlight's effect on the natural world. In Pichwai paintings, night scenes with full moons often symbolize the magical and romantic atmosphere of Vrindavan, where Lord Krishna spent his divine pastimes. 

The moonlight enhances the sacredness of the scene, symbolizing peace, purity, and divine grace. This particular scene represents Krishna's Maharasa on Sharad Purnima, a night of divine celebration when the moon is at its brightest and fullest. According to tradition, Sharad Purnima is the night when Krishna performed the Rasa Lila with the Gopis, filling the world with love, harmony, and transcendental bliss. The interplay of light and dark creates a mesmerizing effect, emphasizing the ethereal beauty of nature under the moonlit sky, while capturing the divine joy and sanctity of this celestial event. Your observation truly highlights the deeper charm and spiritual essence of this painting!
