PrettyRandomColor

Generate pretty color in Mathematica. Ported from David Merfield's randomColor (f02eede).

Based on PrettyRandomColor, PrettyColorize is a useful tool for customizing the color of your figures in Mathematica.

Installation

1. Open the Mathematica user application folder by SystemOpen @ FileNameJoin[{$UserBaseDirectory, "Applications"}];
2. Create a folder called /PrettyRandomColor and place PrettyRandomColor.wl and /Kernel inside.

Usage

• Load package using << PrettyRandomColor`.
• PrettyRandomColor[] generate one random color
• PrettyRandomColor[] takes the following options:
  • Hue restricts the generated color, possible values are:
    • Monochrome, Red, Orange, Yellow, Green, Blue, Purple, Pink;
    • String representing hex, e.g., "#ffffff", "#666";
    • Integer (0 ~ 360) representing hue value.
  • ColorCount specifies the number of random colors to be generated, default to 1.
  • Luminosity a String specifies the luminosity of the color, can be "Bright", "Light", "Dark".
  • Opacity a Real (0 ~ 1) specifies the opacity of the color, default to 1.
  • Seed an Integer or String representing the RNG seed, default to None.

Code example

Graphics[
  Riffle[
    PrettyRandomColor[ColorCount -> 200], 
    Disk[#, 1/40] & /@ RandomReal[{.1, .9}, {200, 2}]
  ],
  PlotRange -> {0, 1},
  ImageSize -> 600
]
