A traditional old-fashioned RYB color wheel

Blue-green is the color that is between green and blue. It belongs to the cyan family of colors.

Variations

Cyan (aqua)

A modern RGB color wheel

Cyan, also called aqua, is the blue-green color that is between blue and green on a modern RGB color wheel.

The modern RGB color wheel replaced the traditional old-fashioned RYB color wheel because it is possible to display much brighter and more saturated colors using the primary and secondary colors of the RGB color wheel. In the terminology of color theory, RGB color space has a much larger color gamut than RYB color space.

The first recorded use of cyan as a color name in English was in 1879.^[1]

Turquoise

The first recorded use of turquoise as a color name in English was in 1573.^[2]

The color "turquoise" is a light tone of blue-green.

Bondi blue is a color belonging to the cyan family of blues. It is very similar to the Crayola crayon color "blue-green".

Apple, Inc. christened the color of the back of the original iMac computer "Bondi Blue" when it was introduced in 1998. It is said to be named for the color of the water at Bondi Beach, in Sydney, Australia.

One definition of the color is in the Munsell color system (Munsell 5BG) although there is wide-spread acceptance and knowledge of the color from the so called blue-green algae which have been recognised and described since the 18th century and probably before that.

Cerulean (/səˈruːliən/), also spelled caerulean, is a shade of blue ranging between azure and a darker sky blue. The first recorded use of cerulean as a colour name in English was in 1590.^[3] The word is derived from the Latin word caeruleus, "dark blue, blue, or blue-green", which in turn probably derives from caerulum, diminutive of caelum, "heaven, sky".^[4]

"Cerulean blue" is the name of a blue-green pigment consisting of cobalt stannate (Co
₂SnO
₄). The pigment was first synthesized in the late eighteenth century by Albrecht Höpfner, a Swiss chemist, and it was known as Höpfner blue during the first half of the nineteenth century. Art suppliers began referring to cobalt stannate as cerulean in the second half of the nineteenth century. It was not widely used by artists until the 1870s when it became available in oil paint.^[5]

The flag of Sri Lanka uses teal

Teal is a greenish-blue color. Its name comes from that of a bird—the Eurasian teal (Anas crecca)—which presents a similarly colored stripe on its head. The word is often used colloquially to refer to shades of cyan in general.

It can be created by mixing cyan into a green base, or deepened as needed with black or gray.^[7] It is also one of the first group of 16 HTML/CSS web colors. In the RGB model used to create colors on computer screens and televisions, teal is created by reducing the brightness of cyan to about one half.

Teal was a fad color during the 1990s, with, among others, many sports teams adopting the color for their uniforms.^[8]^[9]

The blue green damselfish is a species of damselfish.

In human culture

Linguistics

In some languages, blue and green are considered a single color.

Religion

In the iconography of the Virgin of Guadalupe, she is often depicted as wearing a blue-green colored robe. The color is significant to the Mexicas because of the Aztec religion. Also, Blue-green is known as Maya blue in pre-Columbian cultures. In the Nahuatl culture blue represents the center of fire and tonalli. Also sometimes the blue color is diluted so it appears as a turquoise on manuscripts. The color is often used for the representation of Aztec rulers and European kings.^[10]

Politics

Variations of blue-green are the political colors (or one of the political colors) of various political parties, including:
- New Right (Denmark)
- DENK (The Netherlands)
- Brexit Party/Reform UK (United Kingdom)
- People-Animals-Nature (Portugal)
- Justice Party (United States)
In Australia, a loosely-aligned group of independent and minor party candidates that ran in the 2022 Australian federal election were called teal independents for their blend of green and blue (Liberal) politics.
