What is Secondary color?
{{no sources|date=April 2020}} [[Image:AdditiveColorMixing.svg|thumb|250px|After mixing two colors, a secondary color is made.]] '''Secondary colors''' are [[colors]] made from two [[primary colors]]. Secondary colors can be made by mixing [[dye]]s, such as [[ink]] or [[paint]], together. They can also be made when two [[light]]s shine into each other. When mixed with a primary color, a secondary color makes a [[tertiary color]]. ==Secondary colors in color models== ===RGB=== [[RGB]] is the [[color model]] of light. In it, the secondary colors are [[yellow]], mixed from [[red]] and [[green]], [[magenta]], mixed from red and [[blue]], and cyan, mixed from green and blue. [[Computer screen]]s use the primary colors of the RGB color model to show secondary colors. Each screen has tiny [[pixels]] that light up in different primary colors, which blur together to look like a secondary color is being shown. ===CMY=== [[CMY color model|CMY]] is the color model of dyes. The colors in it are like the ones in RGB, but their places are switched; cyan, magenta, and yellow are the primary colors, while red, green, and blue are the secondary colors instead. [[Computer printer|Printers]] use inks based on the CMY primary colors to make the secondary colors that are on the [[picture]]s they print. However, the inks are usually not perfect, so a fourth ink is used with most printers. This is called [[CMYK color model|CMYK]]. [[File:CMYK subtractive color mixing.svg|thumb|When CMY colors are mixed together, the secondary colors are red, green, and blue, which are the primary colors of the RGB model.]] ===Other models=== RYB, or red yellow blue, is an older idea of what the primary and secondary colors are. It was once thought that the secondary colors are [[Orange (color)|orange]], mixed from [[red]] and [[yellow]], [[green]], mixed from yellow and [[blue]], and [[purple]], mixed from red and blue. This way of mixing colors was used for dyes before CMY became widely used. The blue in RYB is usually more of an [[Azure (c
