# Angular Color Picker

<a href="https://badge.fury.io/js/ngx-color-picker"><img src="https://badge.fury.io/js/ngx-color-picker.svg" align="right" alt="npm version" height="18"></a>

This is a simple color picker based on the cool angular2-color-picker by Alberplz.

This documentation is for the latest 5/6.x.x version which requires Angular 5 or newer. For Angular 4 you need to use the latest 4.x.x version. Documentation for the 4.x.x can be found from <a href="https://github.com/zefoy/ngx-color-picker/tree/4.x.x/">here</a>.
