Installation

$ npm install color-schema-test

Usage

Validate data with JSON schema, and develop with types and interfaces.

Validate

Validate by Ajv (JSON schema validator):

import Ajv from "ajv";
import colorSchema from "build/color-schema.json";

const ajv = new Ajv();
const validate = ajv.compile(colorSchema);
const valid = validate(data);

Types & Interfaces

Some types and interfaces:

import { ColorSchema, Palette, Color } from 'color-schema-test';

ColorSchema

Color Schema is a color assets package consisting of a collection of palettes.

interface ColorSchema {
  brandName: string;
  palettes: Palette[];
}

Palette

Color palette is a collection of colors.

interface Palette {
  id?: string;
  name: string;
  type: PaletteType;
  semantic: string | null;
  description?: string;
  colorScheme?: ColorSchemeType;
  usage?: string[];
  colors: Color[] | ContinuousColor[] | colors: Color[][];
  origin?: {
    x: Color[];
    y: Color[];
  };
}

PaletteType

According to different data types and usage scenarios, four different types of color plates are provided.

type PaletteType = "categorical" | "discrete-scale" | "continuous-scale" | "matrix";

ColorSchemeType

Color scheme is described in terms of logical combinations of colors on a color wheel. Different types of schemes, like monochromatic or complementary, are used.

type ColorSchemeType = 
  | "monochromatic"
  | "complementary"
  | "split-complementary"
  | "achromatic"
  | "analogous"
  | "triadic"
  | "tetradic"
  | "polychromatic"
  | "customized";

Color

interface Color {
  model: ColorModel;
  value: ColorValue;
  id?: string;
  name?: string;
  undertone?: Undertone;
  usage?: string[];
}

ColorModel

type ColorModel = "hsl" | "hsv" | "hsi" | "rgb" | "rgba" | "lab" | "lch" | "cmyk";

Undertone

type Undertone = "warm" | "neutral" | "cool";

Dev

npm install
npm run start
