Compute with colors and differenct color spaces

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 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
