A multicolored arc that appears in the sky opposite the sun, typically seen after rain or near large waterfalls, formed by the refraction and dispersion of sunlight through water droplets in the air.
A natural phenomenon characterized by a spectrum of colors arranged in a circular shape, often symbolizing hope or dreams, where the inner color is violet and the outer color is red, with the possibility of a secondary arc displaying the reverse color order surrounding the first.

A thin circular membrane located between the cornea and lens of the eye, responsible for regulating the size of the pupil and controlling the amount of light that enters the eye through its ability to contract and expand.
The colored part of the eye surrounding the pupil, which varies in color among different races and maintains a unique pattern for each individual throughout their life.
A delicate structure in the eye that plays a crucial role in vision by adjusting the aperture of the pupil in response to changes in lighting conditions.
A phenomenon where a faint, white arc appears in the sky, typically caused by the refraction of light through water droplets in mist or fog, often associated with an eerie or otherworldly atmosphere.
A symbolic representation of a rare or ominous occurrence, historically believed to foreshadow conflict or turmoil in society, reflecting the cultural significance attributed to unusual weather patterns.
A rainbow that appears at night, created by the light of the moon rather than the sun, often characterized by its soft, white appearance.
A rare atmospheric optical phenomenon where the moon's illumination causes water droplets to refract light, resulting in a spectral arc in the sky.
A delicate and ethereal arc of color or light that happens during specific lunar conditions, reflecting the interplay between moonlight and moisture in the atmosphere.
