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', ...]

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.
