allc v0.2.0

Allc

A small typescript package for color conversion.

Color Models And Spaces

This library provides these:

• RGB<"sRGB"> (3xnumber)
  • RGBNumber (3xinteger 0..=255)
  • Hex (3xinteger 0..=255)
  • HSL (3xnumber)
  • HSB (3xnumber)
• CIE 1931 XYZ

The following color spaces are in development:

• OKLAB
• OKLCH
• Display P3
• Adobe RGB

More color spaces might be added in the future.

How To Use This Library

You can create colors by using the literal syntax {r: ..., g: ..., b: ...}.

Converting between colors is straight forward. It uses the scheme to{TARGET}From{SOURCE} where {TARGET} and {SOURCE} are color spaces.

This library does not have a fully featured conversion matrix (meaning, you cannot convert every type in every other directly). Instead, do the following:

• Hex ↔ RGBNumber ↔ RGB
• HSL ↔ RGB
• HSV ↔ RGB

From there you can convert to CIE1931XYZ and from there you can convert to any other type.

Guarantees

• This package does not throw.
• Only types and functions are used.
• This package is side effect free (only pay for what you use).

The implementation decisions section is gone; a replacement article will be published on https://trombecher.github.io/.
