Editing GIMP (section)

=== Color ===
There are several ways of selecting colors, including palettes, color choosers and using an eyedropper tool to select a color on the canvas. The built-in color choosers include [[RGB color model|RGB]]/[[HSL and HSV|HSV]]/[[CIELAB color space|LAB]]/[[HCL color space|LCH]] selector or scales, water-color selector, [[CMYK color model|CMYK]] selector and a color-wheel selector. Colors can also be selected using hexadecimal color codes, as used in HTML color selection. GIMP has native support for indexed color and [[RGB color model|RGB]] color spaces; other color spaces are supported using decomposition, where each channel of the new color space becomes a black-and-white image. CMYK, [[Lab color space|LAB]] and [[HSL and HSV|HSV]] ([[hue]], [[Colorfulness|saturation]], [[Lightness|value]]) are supported this way.<ref>{{cite web |title=Separate+ |url=http://cue.yellowmagic.info/softwares/separate.html |last=Yamakawa |first=Yoshinori |date=6 January 2007 |website=Cue.YellowMagic.info |archive-url=https://web.archive.org/web/20070107080439/http://cue.yellowmagic.info/softwares/separate.html |archive-date=7 January 2007 |access-date=2 July 2009 }}</ref><ref>{{cite web |title=Decompose |url=http://docs.gimp.org/2.6/en/plug-in-decompose-registered.html |website=Docs.Gimp.org |access-date=2 July 2009 |archive-date=24 December 2013 |archive-url=https://web.archive.org/web/20131224115305/http://docs.gimp.org/2.6/en/plug-in-decompose-registered.html |url-status=live }}</ref> Color blending can be achieved using the Blend tool, by applying a [[Image gradient|gradient]] to the surface of an image and using GIMP's color modes. Gradients are also integrated into tools such as the brush tool, when the user paints this way the output color slowly changes. There are a number of default gradients included with GIMP; a user can also create custom gradients with tools provided. Gradient plug-ins are also available.
