Coral Dusk

Coral

Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.

Dusk

Dusk occurs at the darkest stage of twilight, or at the very end of astronomical twilight after sunset and just before nightfall. At predusk, during early to intermediate stages of twilight, enough light in the sky under clear conditions may occur to read outdoors without artificial illumination; however, at the end of civil twilight, such lighting is required to read outside. The term dusk usually refers to astronomical dusk, or the darkest part of twilight before night begins.

Coral (color)

The various tones of the color coral are orange, red and pink representations of the colors of those cnidarians known as precious corals.
