Usage

`js
import * as color from "pex-color";

// Hexadecimal
color.toHex([1, 0, 0]);
// => "#FF0000"

color.toHex([1, 0, 0, 0.5]);
// => "#FF000080"

color.toHex([1, 0, 0, 0.5], false);
// => "#FF0000"

color.fromHex(color.create(), "#FF0000");
// => [1, 0, 0, 1]

color.fromHex(new Array(3), "#FF0000");
// => [1, 0, 0]

// CSS
color.toCSSRGB([1, 0, 0, 1]);

API

The "color" primitive is an array of 3 (RGB) or 4 (A) values in the range 0 < x < 1.

API naming follows the following rules:

- fromType(color, ...values) = set a color primitive from Type values
- toType(color, out) = convert a color primitive to an array of Type and optionally set it to out
