# 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`.

```html
<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`.

```ts
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.
