Add a Color Picker in your web-page
HTML Color Pickers are primarily used to select and input colors. The ‹input› elements of type color provide a user interface element that lets a user specify a color, either by using a visual color picker interface or by entering the color into a text field in #rrggbb hexadecimal format.
The ‹input type="color"› defines a color picker.
<input type="color" id="colorpicker">
Providing a default color
You can update the above code to set a default value, so that the color well is pre-filled with the default color and the color picker (if any) will also default to that color.
<input type="color" id="colorpicker" value="#ed6868">
If you don't specify a value, the default is #000000, which is black.

Get the new value of colorpicker when it changes
When you want to get the new color code, you need to attach a handler to the onchange event of your colorpicker.
document.getElementById("cPicker").onchange = function() {
selectedColor = this.value;
}
