  .
  `prizm` is a Haskell library for computing with colors. Specifically
  providing functions for transforming between different color spaces,
  interpolating colors and adjusting the tint, shade, hue, or
  lightness or a color.
  .
  My inspiration for writing this was Sass and Bourbon, both implement
  interesting functions for computing with colors for use in
  stylesheets and I wanted the same thing for use in <http://fvisser.nl/clay/ Clay>.
  .
  /Colour Module/
  .
  There is some overlap with the Haskell Colour Module that already
  exists; however, this library is filling a couple of needs the
  other doesn't satisfy. Primarily transformations and color
  mutations in the CIE L*Ch space.
  .
  /Supported Algorithms & Functions/
  .
  All of these functions operate on color within the CIE L\*Ch
  representation. The percentage values may range between -100
  and 100.

  * sRGB <-> CIE XYZ
  .
  * CIE XYZ <-> CIE L\*ab

  * CIE L\*ab <-> CIE L\*Ch

  * Color interpolation

  * Tinting / Darkening

  * Lightness

  * Hue

  * Chroma/Saturation
