ROYGBIV is an acronym for the sequence of hues commonly described as making up a rainbow: red, orange, yellow, green, blue, indigo, and violet. When making an artificial rainbow, glass prism is used, but this colors of "ROY-G-BIV" are inverted to VIB-G-YOR". There are several mnemonics that can be used for remembering this color sequence, such as the name "Roy G. Biv" or sentences such as "Richard of York Gave Battle in Vain".
In the Renaissance, several artists tried to establish a sequence of up to seven primary colors from which all other colors could be mixed. In line with this artistic tradition, Sir Isaac Newton divided his color circle, which he constructed to explain additive color mixing, into seven colors. [1] Originally he used only five colors, but later he added orange and indigo to match the number of musical notes in the major scale. [2] [3]
The Munsell color system, the first formal color notation system (1905), names only five "principal hues": red, yellow, green, blue, and purple. [4]
Isaac Newton's color sequence (red, orange, yellow, green, blue, indigo, violet) is kept alive today by several popular mnemonics. One is simply the nonsense word roygbiv, which is an acronym for the seven colors. [5] This word can also be envisioned as a person's name, "Roy G. Biv". [6]
Another traditional mnemonic device has been to turn the initial letters of the seven spectral colors into a sentence, most commonly "Richard Of York Gave Battle In Vain" [7] (or the slight alternative "Richard Of York Gained Battles In Vain"). [6] [8] This mnemonic is said to refer to the defeat and death of Richard, Duke of York at the Battle of Wakefield in 1460, [9] or to his son Richard III being defeated at the battle of Bosworth Field in 1485. Another sentence sometimes used is "Read Out Your Good Book In Verse", [10] referring to the Bible.
The mnemonic sentence "Richard Of York Gave Battle In Vain", mentioned above, also appears in the 2003 novel Artemis Fowl and the Eternity Code , third book of the Artemis Fowl series.
Indigo is a term used for a number of hues in the region of blue. The word comes from the ancient dye of the same name. The term "indigo" can refer to the color of the dye, various colors of fabric dyed with indigo dye, a spectral color, one of the seven colors of the rainbow as described by Newton, or a region on the color wheel, and can include various shades of blue, ultramarine, and green-blue. Since the web era, the term has also been used for various purple and violet hues identified as "indigo", based on use of the term "indigo" in HTML web page specifications.
A mnemonic device or memory device is any learning technique that aids information retention or retrieval in the human memory, often by associating the information with something that is easier to remember.
The major system is a mnemonic technique used to help in memorizing numbers.
In color theory, hue is one of the main properties of a color, defined technically in the CIECAM02 model as "the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, orange, yellow, green, blue, violet," within certain theories of color vision.
Color theory, or more specifically traditional color theory, is the historical body of knowledge describing the behavior of colors, namely in color mixing, color contrast effects, color harmony, color schemes and color symbolism. Modern color theory is generally referred to as Color science. While there is no clear distinction in scope, traditional color theory tends to be more subjective and have artistic applications, while color science tends to be more objective and have functional applications, such as in chemistry, astronomy or color reproduction. Color theory dates back at least as far as Aristotle's treatise On Colors. A formalization of "color theory" began in the 18th century, initially within a partisan controversy over Isaac Newton's theory of color and the nature of primary colors. By the end of the 19th century, a schism had formed between traditional color theory and color science.
Opticks: or, A Treatise of the Reflexions, Refractions, Inflexions and Colours of Light is a book by Isaac Newton that was published in English in 1704. The book analyzes the fundamental nature of light by means of the refraction of light with prisms and lenses, the diffraction of light by closely spaced sheets of glass, and the behaviour of color mixtures with spectral lights or pigment powders. Opticks was Newton's second major book on physical science and it is considered one of the three major works on optics during the Scientific Revolution. Newton's name did not appear on the title page of the first edition of Opticks.
A color wheel or color circle is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc.
A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band. Every wave of visible light is perceived as a spectral color; when viewed as a continuous spectrum, these colors are seen as the familiar rainbow. Non-spectral colors are evoked by a combination of spectral colors.
In color science, a color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components. When this model is associated with a precise description of how the components are to be interpreted, taking account of visual perception, the resulting set of colors is called "color space."
The Newton disc, also known as the disappearing colour disc, is a well-known physics experiment with a rotating disc with segments in different colours appearing as white when it's spun rapidly about its axis.
Rainbow Raider is a supervillain appearing in comic books by DC Comics. His real name is a pun based on the acronym "ROYGBIV", a mnemonic for the colors of a rainbow. He is a minor, though recurring, enemy of the Flash and other heroes.
VIBGYOR (Violet–Indigo–Blue–Green–Yellow–Orange–Red) is a popular mnemonic device used for memorizing the traditional optical spectrum.
A color picker is a graphical user interface widget, usually found within graphics software or online, used to select colors and, in some cases, to create color schemes. Operating systems such as Microsoft Windows or macOS have a system color picker, which can be used by third-party programs.
Color analysis, also known as personal color analysis (PCA), seasonal color analysis, or skin-tone matching, is a term often used within the cosmetics and fashion industry to describe a method of determining the colors of clothing, makeup, hair style that harmonizes with a person's skin complexion, eye color, and hair color for use in wardrobe planning and style consulting.
There are numerous variations of the color purple, a sampling of which is shown below.
Since the introduction of Crayola drawing crayons by Binney & Smith in 1903, more than two hundred colors have been produced in a wide variety of assortments. The line has undergone several major revisions, notably in 1935, 1949, 1958, and 1990. Numerous specialty crayons have also been produced, complementing the basic Crayola assortment.
Colors is a "word jazz" album by voice-over and recording artist Ken Nordine. It was commissioned by the Fuller Paint Company to write radio advertisement spots, but after a few commercials became popular, it evolved to become an album of 34 songs. Each track personifies a different color or hue.
"ROY G BIV BBT" is a song by Alaska Thunderfuck, released in 2021. The song has been described as a "pride anthem".
