Overview

Cvet (Russian word for "color", pronounced /tsvet/) is a color tool for customizing and picking colors easily for your projects. This package includes various types for typescript-friendly development.

Install

$ npm install -D @cvet/types typescript
$ yarn add --dev @cvet/types typescript

Usage

To work with types that this package offers you can either use cvet package that has following types imported or install this package for the use without the tool:

import type { HEX } from "cvet/types"; // with tool usage
import type { HEX } from "@cvet/types"; // with package usage

const color: HEX = "#FF0000";

Types

Package offers various types for most of the color models: HEX, RGB, RGBA, CMYK, HSL HSLA.

With these you can define colors like:

const hex: HEX = "#FF0000";
const safeHex: HEX.Safe = "#FF0000"; // Is a verbose equivalent to HEX type
const unsafeHex: HEX.Unsafe = "#BADHEX"; // Accepts any string

const amazingRgb: RGB = { r: 255, g: 0, b: 0 };
const notSoAmazingRgb: RGB = { r: 256, g: 0, b: 0 }; // Error, only 0-255
const safeRgb: RGB.Safe = { r: 255, g: 0, b: 0 }; // Is a verbose equivalent to RGB type
const weirdRgb: RGB.Unsafe = { r: -299, g: 989, b: 0 }; // Accepts any numbers
const amazingRgba: RGBA = { r: 255, g: 0, b: 0, a: 100 };

const cmyk: CMYK = { c: 0, m: 100, y: 100, k: 0 };
const differentCmyk: CMYK = { c: 0, m: 1, y: 1, k: 0 };
// Won't return error because the type is number,
// CMYK can be 0-1, 0-100 or any other format,
// depends on its usage in other packages

const hsl: HSL = { h: 120, s: 100, l: 50 };
const hsla: HSLA = { h: 120, s: 100, l: 50, a: 10 };
const differentHsl: HSL = { h: 0.33, s: 1, l: 0.5 };
const differentHsla: HSLA = { h: 0.33, s: 1, l: 0.5, a: 0.1 };
// Acts the same as CMYK as HSL has different
// usage cases

Also there are enumerated units such as Amount, Degrees, Hexadecimal, HexChar:

• Amount accepts numbers 0-100
• Degrees accepts numbers 0-360
• Hexadecimal accepts numbers 0-255
• HexChar accepts 0-F string characters as presented in HEX color model

Note HexChar isn't used in safe HEX type, see this stackoverflow question to know why.

Color models

Of course I'd want to include various types for defining color models: ColorType, Color, ColorMap:

• ColorType holds names of color models supported by cvet: "HEX" | "RGB" | "HSL" | "CMYK" | "MAP"
• Color enumerates all of the color models listed above so that it accepts them: HEX | RGB | HSL | CMYK | ColorMap
• ColorMap is used as the recommendation for the standalone color model - RGB, use it for conversion
