# COLOR TOOLS

## Description

Set of classes used to convert colors and calculate color difference.

---

## Features

* ### Model conversion:

  - xy,

  - xyY,

  - XYZ,

  - L\*ab,

  - L\*uv,

  - L\*CH.

  - L\*CH UV.

  - HSV,

  - HSL,

  - RGB for primaries \*:

    - Adobe 1998 RGB,

    - Apple RGB,

    - Best RGB,

    - Beta RGB,

    - Bruce RGB,

    - CIE RGB,

    - ColorMatch RGB,

    - Don RGB 4,

    - ECI RGB v2,

    - Ekta Space PS5,

    - NTSC RGB,

    - PAL/SECAM RGB,

    - ProPhoto RGB,

    - Radiance RGB,

    - SMPTE-C RGB,

    - sRGB,

    - WideGamutRGB.

  ---

  \* custom-defined primaries also supported.

* ### Chromatic adaptation transformations matrices:

  - XYZ Scaling,

  - Von Kries,

  - Bradford,

  - CMCCAT2000,

  - CIECAT02,

  - Sharp.

* ### White point dictionary of standard illuminants:

  *(2° and 10° standard observer)*

  - A,

  - B,

  - C,

  - D50, D55, D65, D75, D93,

  - E,

  - F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12,

  - LED_B1, LED_B2, LED_B3, LED_B4, LED_B5, LED_BH1, LED_RGB1, LED_V1, LED_V2. \*

  ---

  \* all LED-based illuminants have 2° standard observer only.

* ### DeltaE difference:

  Check color distance in various algorithms:

  - CIE76,

  - CIE94,

  - CIE00 (CIEDE2000),

  - CMC l:c.

* ### Contrast ratio calculation.
