Component API

Color

Color controls what color is active on the color picker. You can use this to initialize the color picker with a particular color, or to keep it in sync with the state of a parent component.

Color accepts either a string of a hex color '#333' or a object of rgb or hsl values { r: 51, g: 51, b: 51 } or { h: 0, s: 0, l: .10 }. Both rgb and hsl will also take a a: 1 value for alpha. You can also use transparent.

<color-sketch color="#fff" (onChangeComplete)="handleChangeComplete($event)"></color-sketch>

In this case, the color picker will initialize with the color #fff. When the color is changed, handleChangeComplete will fire and set the new color to state.

onChange

Pass a function to call every time the color is changed. Use this to store the color in the state of a parent component or to make other transformations.

Keep in mind this is called on drag events that can happen quite frequently. If you just need to get the color once use onChangeComplete.

import { Component } from '@angular/core';
import { ColorEvent } from 'ngx-color';

@Component({
  selector: 'selector-name',
  template: ` <color-sketch (onChange)="handleChange($event)"></color-sketch> `,
})
export class NameComponent {
  constructor() {}

  handleChange($event: ColorEvent) {
    console.log($event.color);
    // color = {
    //   hex: '#333',
    //   rgb: {
    //     r: 51,
    //     g: 51,
    //     b: 51,
    //     a: 1,
    //   },
    //   hsl: {
    //     h: 0,
    //     s: 0,
    //     l: .20,
    //     a: 1,
    //   },
    // }
  }
}

onChangeComplete

Pass a function to call once a color change is complete.
