ColorFunction is an option for various graphics functions which specifies a function to apply to values to determine the color to use for a particular , region.
ColorFunction is an option for Plot3D, ListPlot3D, DensityPlot, ContourPlot, Raster and related functions.
The arguments provided for the function specified by ColorFunction are always in the range 0 to 1.
For three-dimensional, density and contour plots, the arguments correspond to scaled values.
The function specified by ColorFunction must return a CMYKColor, GrayLevel, Hue or RGBColor directive.
Automatic yields a range of gray levels.
Hue yields a range of colors.
In three-dimensional graphics, ColorFunction is used only with the option setting Lighting
See the Mathematica book: Section 1.9.6, Section 1.9.6, Section 1.9.7, Section 2.9.2.
See also: Lighting, ColorOutput.
Here is a density plot colored according to the Hue directive.
Evaluate the cell to see the graphic.
