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-color-kit-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 | | inputFocus | Function | Event | FocusEvent Object | | inputBlur | Function | Event | FocusEvent Object |

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.
