{{main|Primary color}}

Color theory asserts three pure primary colors that can be used to mix all possible colors. These are sometimes considered as red, yellow and blue ([[RYB color model|RYB]]) or as red, green and blue ([[RGB color model|RGB]]).{{Citation needed|date=April 2024}} Ostensibly, any failure of specific [[paint]]s or [[ink]]s to match this ideal performance is due to the impurity or imperfection of the colorants. In contrast, modern color science does not recognize universal primary colors (no finite combination of colors can produce all other colors) and only uses primary colors to define a given [[color space]].<ref name="Handprint1"/> Any three primary colors can mix only a limited range of colors, called a [[gamut]], which is always smaller (contains fewer colors) than the full range of colors humans can perceive.<ref>{{Cite web|title=Traditional and Modern Colour Theory Part 1: Modern Colour Theory|url=http://www.huevaluechroma.com/112.php|access-date=2021-10-15|language=en-AU}}</ref> Primary colors also can't be made from other colours as they are inherently pure and distinct.<ref>{{Cite web|title=3 Basic Primary Colors | Additive and Subtractive Color Mixing|url=https://www.geeksforgeeks.org/primary-colors/|access-date=2025-01-10|language=en-USA}}</ref>
