Past Riddle #78 (Jan 29, 2024)

In ethereal realms, I dance unseen, A bridge of spectral light, silently serene. Born from tears of the sky, embraced by the sun's gold kiss, In sevenfold mystery, my existence is a transient bliss. Neither fabric can hold me nor can hands grasp, Yet in my fleeting arc, a promise is clasped. A painter's palette in the heavens, briefly unfurled, I am the fleeting symphony of the watery world. What am I?
