 * Value types for the constructor of {@link Color}.
 * These types are extended from [colord](https://www.npmjs.com/package/colord) with some PixiJS-specific extensions.
 *
 * Possible value types are:
 * - [Color names](https://www.w3.org/TR/css-color-4/#named-colors):
 *   `'red'`, `'green'`, `'blue'`, `'white'`, etc.
 * - RGB hex integers (`0xRRGGBB`):
 *   `0xff0000`, `0x00ff00`, `0x0000ff`, etc.
 * - [RGB(A) hex strings](https://www.w3.org/TR/css-color-4/#hex-notation):
 *   - 6 digits (`RRGGBB`): `'ff0000'`, `'#00ff00'`, `'0x0000ff'`, etc.
 *   - 3 digits (`RGB`): `'f00'`, `'#0f0'`, `'0x00f'`, etc.
 *   - 8 digits (`RRGGBBAA`): `'ff000080'`, `'#00ff0080'`, `'0x0000ff80'`, etc.
 *   - 4 digits (`RGBA`): `'f008'`, `'#0f08'`, `'0x00f8'`, etc.
 * - RGB(A) objects:
 *   `{ r: 255, g: 0, b: 0 }`, `{ r: 255, g: 0, b: 0, a: 0.5 }`, etc.
 * - [RGB(A) strings](https://www.w3.org/TR/css-color-4/#rgb-functions):
 *   `'rgb(255, 0, 0)'`, `'rgb(100% 0% 0%)'`, `'rgba(255, 0, 0, 0.5)'`, `'rgba(100% 0% 0% / 50%)'`, etc.
 * - RGB(A) arrays:
 *   `[1, 0, 0]`, `[1, 0, 0, 0.5]`, etc.
 * - RGB(A) Float32Array:
 *   `new Float32Array([1, 0, 0])`, `new Float32Array([1, 0, 0, 0.5])`, etc.
 * - RGB(A) Uint8Array:
 *   `new Uint8Array([255, 0, 0])`, `new Uint8Array([255, 0, 0, 128])`, etc.
 * - RGB(A) Uint8ClampedArray:
 *   `new Uint8ClampedArray([255, 0, 0])`, `new Uint8ClampedArray([255, 0, 0, 128])`, etc.
 * - HSL(A) objects:
 *   `{ h: 0, s: 100, l: 50 }`, `{ h: 0, s: 100, l: 50, a: 0.5 }`, etc.
 * - [HSL(A) strings](https://www.w3.org/TR/css-color-4/#the-hsl-notation):
 *   `'hsl(0, 100%, 50%)'`, `'hsl(0deg 100% 50%)'`, `'hsla(0, 100%, 50%, 0.5)'`, `'hsla(0deg 100% 50% / 50%)'`, etc.
 * - HSV(A) objects:
 *   `{ h: 0, s: 100, v: 100 }`, `{ h: 0, s: 100, v: 100, a: 0.5 }`, etc.
 * - {@link Color} objects.
