Most of us think of rainbows as arches that stretch across the sky, but in reality, every rainbow forms a complete circle. That circle is centered on the point in the sky directly opposite the sun — the same direction your shadow points. From the ground, the horizon blocks the lower half of that circle, so you usually see only the rainbow's upper arc. But there are ways to see more of the hidden circle.
The prism and color spectrum on Pink Floyd's 1973 album The Dark Side of the Moon is arguably the most iconic rainbow in rock history. The original album artwork, designed by Storm Thorgerson, depicts a beam of white light entering a triangular prism from the left and emerging on the right as a rainbow — though it omits the indigo band typically included in a full spectrum.
