OklabColor constructor

const OklabColor(
  1. double lightness,
  2. double chromaticityA,
  3. double chromaticityB, [
  4. int alpha = 255,
])

A color in the Oklab color space.

lightness, chromaticityA, and chromaticityB's normal range is 0.0 to 1.0, but some colors may fall slightly outside of it.

alpha must be >= 0 and <= 255.

Implementation

const OklabColor(
  this.lightness,
  this.chromaticityA,
  this.chromaticityB, [
  int alpha = 255,
])  : assert(alpha >= 0 && alpha <= 255),
      super(alpha: alpha);
