Sample code

array(
    'name'          => 'Color picker',
    'id'            => 'field_id',
    'type'          => 'color',
    // Add alpha channel?
    'alpha_channel' => true,
    // Color picker options. See here: https://automattic.github.io/Iris/.
    'js_options'    => array(
        'palettes' => array( '#125', '#459', '#78b', '#ab0', '#de3', '#f0f' )
    ),

Data

This field simply saves a the hex value of the picked color in the database.

If the field is cloneable, then the value is stored as a serialized array in a single row in the database.

Template usage

To get the field value, use the following code:

$value = rwmb_meta( $field_id );
echo $value;

The rwmb_meta() function returns the color code. If you want to display the actual color, use this code:

rwmb_the_value( $field_id );

which displays the color as a single dot like this:
