The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Styling individual links on a page. Further information: Template:Colored link. You can set the color of an individual link or set of links on a page (rather than a global change to the style of all links on Wikipedia) as follows.
In the CMYK color model used in printing, violet is created with a combination of magenta and cyan pigments, with more magenta than cyan. On the RGB / CMY ( K) color wheel, violet is located between blue and magenta. Violet is closely associated with purple.
Web colors are colors used in displaying web pages on the World Wide Web; they can be described by way of three methods: a color may be specified as an RGB triplet, in hexadecimal format (a hex triplet) or according to its common English name in some cases. A color tool or other graphics software is often used to generate color values.
On the RGB color wheel, "azure" ( hexadecimal #0080FF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a 50% of green light to a 100% of blue light.
In the traditional RYB color model, the complementary color pairs are red – green, yellow – purple, and blue – orange. Opponent process theory suggests that the most contrasting color pairs are red–green and blue–yellow. The black - white color pair is common to all the above theories.
In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both. In the RGB color model used in computer and television screens, purple is created by mixing red and blue light in order to create colors that appear similar to violet light.
A simulated example of additive color mixing in the RGB model. The primaries red, green, and blue combine pairwise to produce the additive secondaries cyan, magenta, and yellow. Combining all three primaries (center) produces white.
Thus, electric purple is the purest and brightest purple that it is possible to display on a computer screen. Its RGB code is (191, 0, 255). An old name for this color, used by Robert Ridgway in his 1912 book on color nomenclature, Color Standards and Color Nomenclature, is true purple.
To make a word have colour, use: <span style="color:hex triplet or colour name">text</span>. Note that you can't use the British spelling, "colour", in this context. Examples: <span style="color:red">red writing</span> shows as red writing. <span style="color:#0f0">green writing</span> shows as green writing.
