bs-randomColor

BuckleScript bindings for davidmerfield/randomColor (library for generating attractive random colors). This implementation gives couple functions:

• randomColor()
  Generate single color.
• randomColorMultiple()
  Generate multiple colors.
• randomColorHslArray()
  Generate single color with tuple as an output ((int, int, int)).
• randomColorRgbArray()
  Generate single color with tuple as an output ((int, float, float)).

How to install

yarn add bs-randomcolor

Then add bs-randomcolor as a dependency to bsconfig.json:

"bs-dependencies": [
+  "bs-randomcolor"
]

Supported options

• hue
  Controls the hue of the generated color. Possible values:

  • HueRed
  • HueOrange
  • HueYellow
  • HueGreen
  • HueBlue
  • HuePurple
  • HuePink
  • HueMonochrome

• hueHex
  Hexadecimal value of any color which will be used instead of "hue" option. The randomColor will extract its hue value and use that to generate colors.

• luminosity
  Controls the luminosity of the generated color. Possible values:

  • LuminosityBright (default)
  • LuminosityLight
  • LuminosityDark

• count
  An integer which specifies the number of colors to generate.
  Notice: option available only for randomColorMultiple().

• seed
  An integer or string which when passed will cause randomColor to return the same color each time.

• format
  Specifies the format of the generated color. Possible values:

  • FormatHex (default)
  • FormatRgb
  • FormatRgba
  • FormatHsl
  • FormatHsla
  • FormatRgbArray (available only for randomColorRgbArray())
  • FormatHslArray (available only for randomColorHslArray())

• alpha
  A decimal between 0 and 1. Only relevant when using a format with an alpha channel (FormatRgba and FormatHsla). Defaults to a random value.

Example usages:

open RandomColorRe;

randomColor(); // "#f9a05c"
randomColor(~seed="test", ~format=FormatRgb, ()); // "rgb(249, 160, 92)"
randomColor(~seed="test", ~format=FormatRgba, ~alpha=0.2, ()) // "rgba(249, 160, 92, 0.2)"
randomColor(~seed="test", ~hue=HuePurple, ~luminosity=LuminosityDark, ()) // "#070707"
randomColorMultiple(~seed="test123", ~count=3, ()) // [|"#b6f453", "#4cdbb2", "#f9d759"|]
randomColorMultiple(~seed="test123", ~count=3, ()) // [|"#b6f453", "#4cdbb2", "#f9d759"|]
randomColorRgbArray(~seed="test", ~hue=HueRed, ()) // (137, 4, 44)
randomColorHslArray(~seed="test", ()) // (71, 94.17, 23.69)
