            openSucker(isOpen) {
                if (isOpen) {
                    // ... canvas be created
                    // this.suckerCanvas = canvas
                    // this.suckerArea = [x1, y1, x2, y2]
                } else {
                    // this.suckerCanvas && this.suckerCanvas.remove

Options

Name	Type	Default	Description
theme	String	`dark`	`dark` or `light`
color	String	`#000000`	`rgba` or `hex`
colors-default	Array	`['#000000', '#FFFFFF', '#FF1900', '#F47365', '#FFB243', '#FFE623', '#6EFF2A', '#1BC7B1', '#00BEFF', '#2E81FF', '#5D61FF', '#FF89CF', '#FC3CAD', '#BF3DCE', '#8E00A7', 'rgba(0,0,0,0)']`	like `['#ff00ff', '#0f0f0f', ...]`
colors-history-key	String	`vue-colorpicker-history`
sucker-hide	Boolean	`true`	`true` or `false`
sucker-canvas	HTMLCanvasElement	`null`	like `document.createElement('canvas')`
sucker-area	Array	`[]`	like `[x1, y1, x2, y2]`

color is one-way data flow, so you can't use v-model. why? because you'll listen changeColor event do more things, so i think it's not necessary here.

Events

Name	Type	Args	Description
changeColor	Function	color	`{ rgba: {}, hsv: {}, hex: ''}`
openSucker	Function	isOpen	`true` or `false`

if you want use sucker, then openSucker, sucker-hide, sucker-canvas, sucker-area is necessary. when you click sucker button, you can click it again or press key of esc to exit.
