Blue-green

My nails are blue-green.

Tom's least favorite color is blue-green.

Cold methane gas is responsible for the blue-green color of Uranus.

Uranus is a large, plain, blue-green planet which can only be seen from the Earth with the unaided eye on a clear, dark night.

The temperature in Uranus' upper atmosphere is so cold that the methane condenses and forms a thin cloud layer which gives the planet its blue-green appearance.

Neptune and Uranus are very much alike. They are both large gas planets that look like big blue-green balls in the sky.

He only likes Polish girls with blue-green eyes.

Andrew has a blue-green T-shirt and green pants.

Then about 2.3 to 2.5 billion years ago, during the Proterozoic Eon, blue-green algae called cyanobacteria, living in Earth’s shallow oceans, began emitting enough oxygen through photosynthesis to create the permanently oxygenated atmosphere that keeps us alive today.

Uranus tilts over so far on its axis that it rotates on its side. Because of this, its poles are sometimes pointed almost directly at the Sun. Uranus' atmosphere is made up of hydrogen, helium, and methane. The temperature in the upper atmosphere is very cold. The cold methane gas is what gives Uranus its blue-green color. The rapid rotation of Uranus causes winds up to 600 kilometers per hour to blow in its atmosphere. Uranus has eleven known rings which contain dark, boulder-sized particles. Uranus has 27 named moons. Some of these moons are less than 100 kilometers wide and black as coal.
