Package Hackage Nightly LTS
Color Hackage Nightly Nightly

Description

There is a clear separation between color models, color spaces and alternative representations of color spaces. All are distinct at the type level. The goal is to prevent mixups of incompatible color types as well as utilize type information for conversion between them.

Currently supported:

  • Color models:

    • Y
    • RGB
    • HSI
    • HSL
    • HSV
    • YCbCr
    • CMYK

  • Color spaces and arbitrary conversions between them:

    • Y - luminance

    • Y' - luma

    • CIE XYZ

    • CIE L*a*b*

    • RGB:

      • sRGB - both standardized and derived

      • AdobeRGB - both standardized and derived

      • ITU: Rec470, Rec601 and Rec709

      • Alternative representations:

        • HSI
        • HSL
        • HSV
        • YCbCr
        • CMYK

  • Illuminants:

    • CIE1931 - 2 degree observer
    • CIE1964 - 10 degree observer
    • Some common alternatives

  • Chromatic adaptation:

    • VonKries adaptation with transformations:

      • VonKries
      • Bradford (default)
      • Fairchild
      • CIECAM02
      • CMCCAT2000

  • Color Standards:

    • RAL
    • SVG
