RandomColor[]

gives a pseudorandom color directive in the RGBColor space.

RandomColor[n]

gives n pseudorandom colors.

RandomColor[model]

gives a color from the specified model.

RandomColor[model,n]

gives n colors.

RandomColor[model,{n1,n2,…}]

gives an array of colors.

Details and Options

  • RandomColor tries to choose colors from a uniform probability distribution in the gamut of the specified model.
  • The model can be any color directive, such as RGBColor[r,g,b] and RGBColor[r,g,b,a]. Each of the channel expressions r, g, b, and a can be of the form:
  • cconstant value
    _any allowed value uniformly distributed
    distany value following the distribution dist
  • For unbounded spaces such as LABColor, LCHColor, LUVColor, and XYZColor, channel values are limited to the visual range.
  • RandomColor gives a different sequence of pseudorandom colors whenever it is run. You can start with a particular seed using SeedRandom.
  • RandomColor by default generates colors in the color space given by model. Use the option ColorSpace->cspace to convert colors to the color space cspace.

Basic Examples  (2)

A random color:

Wolfram Language code: RandomColor[]

A list of three random colors:

Wolfram Language code: RandomColor[3]

Scope  (5)

A list of random colors from the full RGB space:

Wolfram Language code: RandomColor[10]

A list of random RGB colors using an explicit model:

Wolfram Language code: RandomColor[RGBColor[_, _, _], 5]

A list of random RGBA colors:

Wolfram Language code: RandomColor[RGBColor[_, _, _, _], 5]

Give a model that constrains to a fixed channel value:

Wolfram Language code: RandomColor[RGBColor[1, _, _], 5]

Use a symbolic distribution for a color channel:

Wolfram Language code: RandomColor[RGBColor[1, NormalDistribution[.6, .2], 1], 10]

An array of random RGB colors using an explicit model:

Wolfram Language code: RandomColor[RGBColor[_, _, _], {5, 7}]
Wolfram Language code: Image[%]

Options  (1)

ColorSpace  (1)

By default, colors are returned as RGBColor directives:

Wolfram Language code: RandomColor[]//InputForm

Specify a different color space:

Wolfram Language code: RandomColor[ColorSpace -> "LAB"]//InputForm

Sample in one color space but return the result in another space:

Wolfram Language code: RandomColor[Hue[0, _, _], ColorSpace -> "RGB"]//InputForm

Applications  (2)

Generate a graphic using a random color:

Wolfram Language code: Graphics[{RandomColor[], Disk[]}]

Generate a graphic with multiple directives of random colors:

Wolfram Language code: Graphics[Table[{RandomColor[], Disk[RandomReal[{.1, .9}, 2], 1 / 20]}, {i, 100}], PlotRange -> {0, 1}]

Choose colors for each plot randomly:

Wolfram Language code: Plot[{Sin[x], Sin[2x], Sin[3x]}, {x, 0, 10}, PlotStyle -> RandomColor[3]]

Properties & Relations  (1)

Get five colors from a specific color scheme defined in ColorData:

Wolfram Language code: ColorData["CherryTones"] /@ RandomReal[1, 10]
