What gives coral its bright colors?

The body of a coral polyp is clear, and zooxanthellae algae are pigment cells that take up residence inside the coral's tissue. It's an innate mixture of these cells that give coral its generous display of color. Another factor that distinguishes coral color is light.

Regarding this, what makes the coral different colors?

Colorful corals contain symbiotic algae, or zooxanthellae, which are brownish or green because of the photosynthetic pigment called “chlorophyll”. The chlorophyll is responsible for the brown or green coloration. These pigments can appear red, purple, blue, mauve or other colors.

What is the cause of coral bleaching?

Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. In 2005, the U.S. lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event.
