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

Variations

Cyan

Cyan 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 color turquoise is that of the semi-precious stone turquoise, which is a light tone of blue-green.

Its first recorded use as a color name in English is from 1573.^[2]

Bondi blue belongs 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

Cerulean ( /səˈruːliən/ ), also spelled caerulean, is a variety of the hue of blue that may range from a light azure blue to a more intense sky blue, and may be mixed as well with the hue of green. 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]

Teal as a tertiary color
green
teal
blue

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.

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

In nature

Blue-green algae are a phylum of bacteria that obtain their energy through photosynthesis.
The blue green damselfish is a species of damselfish.
Glacial flour, powdered rock, can turn a lake to a blue-green color.

In culture

In some languages, blue and green are considered a single color.
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]
Variations of blue-green are the political colors (or one of the political colors) of various political parties, including:
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.

Red-violet refers to a rich color of high medium saturation about 3/4 of the way between red and magenta, closer to magenta than to red. In American English, this color term is sometimes used in color theory as one of the purple colors—a non-spectral color between red and violet that is a deep version of a color on the line of purples on the CIE chromaticity diagram.

Spring green is a color that was traditionally considered to be on the yellow side of green, but in modern computer systems based on the RGB color model is halfway between cyan and green on the color wheel.

In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.

Varieties of the color green may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.

Varieties of the color red may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors are shown below.

Shades of brown can be produced by combining red, yellow, and black pigments, or by a combination of orange and black—illustrated in the color box. The RGB color model, that generates all colors on computer and television screens, makes brown by combining red and green light at different intensities. Brown color names are often imprecise, and some shades, such as beige, can refer to lighter rather than darker shades of yellow and red. Such colors are less saturated than colors perceived to be orange. Browns are usually described as light or dark, reddish, yellowish, or gray-brown. There are no standardized names for shades of brown; the same shade may have different names on different color lists, and sometimes one name can refer to several very different colors. The X11 color list of web colors has seventeen different shades of brown, but the complete list of browns is much longer.
