84 Things That Are Blue

John Spacey, November 05, 2021

Blue is both the most common color in nature and the least common. As the dominant color in the sky, blue is the background color for daytime. As the color of large bodies of water, the entire planet appears to be blue from space. Beyond sky and sea, blue is a relatively rare color whereby few plants, animals or minerals are blue. For this reason, blue was the last major color to be widely available as a pigment. The following are examples of things that are naturally blue.

Aquamarine	Blackberries
Blue Algae (Cyanobacteria)	Blue Cheese
Blue Diamonds	Blue Iguanas

Some of the things in the list above change color depending on conditions. For example, oceans, waterfalls, icebergs or clouds can look blue depending on weather and lighting conditions.
