Installation

To install this library, run:

$ npm install ng-color --save

How to use

To use this library in your AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';

// Import your library
import { NgColorModule } from 'ng-color';

@NgModule({
    declarations: [AppComponent],
    imports: [
        BrowserModule,
        NgColorModule, // Inlude in @NgModule
    ],
    providers: [],
    bootstrap: [AppComponent],
})
export class AppModule {}

Once your library is imported, you can use the component in your Angular application shown below.

Color Pickers

Box

What it looks like is shown in the header

<ng-color-box [(ngModel)]="color"></ng-color-box>

<ng-color-box (ngModelChange)="colorChange($event)"></ng-color-box>

Circle

What it looks like is shown in the header

<ng-color-circle [(ngModel)]="color"></ng-color-circle>

<ng-color-circle (ngModelChange)="colorChange($event)"></ng-color-circle>

NgModel and setting the initial color

The ngModel is of the following format. You can use two-way or one-way binding:

export interface ColorOutput {
    rgb: Rgb;
    hex: number;
    hexString: string;
    hsl: Hsl;
}

Or equivalently:

export interface ColorOutput {
    rgb: {
        red: number; // 0 - 255
        green: number; // 0 - 255
        blue: number; // 0 - 255
    };
    hex: number; // 0 - 16777215
    hexString: string; // #000000 - #ffffff
    hsl: {
        hue: number; // 0 - 360
        saturation: number; // 0 - 100
        lightness: number; // 0 - 100
    };
}

Setting these partially also works, this library will resolve all the other components out on the next change detection cycle.

Therefore, you can set the initial color of the picker by doing:

this.myColor = {
    hexString: '#ff56d3',
};

In the html:

<ng-color-box [(ngModel)]="myColor"></ng-color-box>
