• Red is equivalent to RGBColor [1,0,0].

• Red is a symbol that represents the color red in graphics or style specifications. Color specifications in the Wolfram Language can appear explicitly inside a Graphics or Graphics3D expression (e.g. Graphics [{Red,Disk []}]), in which case they affect all subsequent expressions until another specification overrides them. They can also be used as part of an option specification, either singly (e.g. Plot [Sin [x],{x,0,2Pi },PlotStyle->Red]) or as part of a Directive compound expression (e.g. Plot [Cos [x],{x,0,2Pi },PlotStyle->Directive [Thick ,Red]]). Finally, they can appear inside Style wrappers that affect the appearance of text, equations, and notebook cells (e.g. Style ["hello",Red]).
• Red is a color located at one of the corners of the RGB color cube and evaluates to RGBColor [1,0,0].
• Named symbols for other colors include Green , Blue , Black , White , Gray , Cyan , Magenta , Yellow , Brown , Orange , Pink , and Purple , as well as their LightRed etc. variants. Arbitrary colors can be input using Hue , RGBColor , CMYKColor , LABColor , LUVColor , or XYZColor . Colors can be modified using Lighter , Darker , and Blend . Colors may be converted between different systems using ColorConvert . The appearance of colors appearing in Graphics3D objects may be controlled using Glow , Specularity , and Lighting . The transparency of colored graphics objectives can be specified using Opacity . ColorData can be used to give a function that generates colors in a named color scheme.
