Breath of the wild has single, and double rainbows that randomly pop up in the distance.
Shooting stars can be followed to a star fragment at their impact site. Shooting stars are Masonic symbolism.

Pike, in Morals and Dogma in the 25th degree, Knight of the Brazen Serpent, says of the symbol,
The Blazing Star in our Lodges, we have already said, represents Sirius, Anubis, or Mercury, Guardian and Guide of Souls. Our Ancient English brethren also considered it an emblem of the Sun. In the old Lectures they said: “The Blazing Star or Glory in the center refers us to that Grand Luminary the Sun, which enlightens the Earth, and by its genial influence dispenses blessings to mankind.”
Pike, in an earlier degree (the Apprentice) says that The Blazing Star in the center is said to be “an emblem of Divine Providence, and commemorative of the star which appeared to guide the wise men of the East to the place of our Savior’s nativity.” He goes on to say, “[t]he Blazing Star or Glory in the center refers us to that grand luminary, the Sun, which enlightens the earth, and by its genial influence dispenses blessings to mankind.” They called it also in the same lectures, an emblem of PRUDENCE. The word Prudentia means, in its original and fullest signification, Foresight; and, accordingly, the Blazing Star has been regarded as an emblem of Omniscience, or the All-seeing Eye, which to the Egyptian Initiates was the emblem of Osiris…”
Gage, in Builders Magazine (1915), says of the symbol that it is the “seed and the source of all life and eternal life.”
The Blazing Star is one of the three ornaments of the masonic lodge.
