Customising Wordpress Color Picker

Question

Is there any way to customize the Wordpress 3.8 color picker (on the custom field types) to use only colors i will define?

I need to have only 6 colors for a client, but they do not want to have all those colors, apart from 6 gradient colors.

Will be greatful for any help... I have been trying to do it for several days, but no positive solution:(

Thank you

Wordpress 3.5+ uses the Iris colorpicker which has several options available for use.

When initializing the object just assign the palettes option with an array of colors.

var colorOptions = {
    // show a group of common colors beneath the square
    // or, supply an array of colors to customize further
    palettes: ['#4444,44','#ff2255','#559999','#99CCFF','#00c1e8','#F9DE0E','#111111','#EEEEDD']
};

jQuery('.my-color-picker-class').wpColorPicker(colorOptions);

If your using TinyMCE editor you can modify the color palette like so.

function my_mce4_options( $init ) {
    $custom_colours = '
        "e14d43", "Color 1 Name",
        "d83131", "Color 2 Name",
        "ed1c24", "Color 3 Name",
        "f99b1c", "Color 4 Name",
        "50b848", "Color 5 Name",
        "00a859", "Color 6 Name"
    ';

    $init['textcolor_map'] = '['.$custom_colours.']';

    // Set number of color rows
    $init['textcolor_rows'] = 3;
    // Set number of color columns
    $init['textcolor_cols'] = 2

    return $init;
}
add_filter('tiny_mce_before_init', 'my_mce4_options');

We need to wp_enqueue_script the script and wp_enqueue_style the style with add_action to the functions.php file. Just include a jQuery file and stylesheet file by this script.

// Register Scripts & Styles in Admin panel
function custom_color_picker_scripts() {
wp_enqueue_style( 'wp-color-picker' );
wp_enqueue_script( 'iris', admin_url( 'js/iris.min.js' ), array( 'jquery-ui-draggable', 'jquery-ui-slider', 'jquery-touch-punch' ), false, 1 );
wp_enqueue_script( 'cp-active', plugins_url('/js/cp-active.js', __FILE__), array('jquery'), '', true );

}
add_action( 'admin_enqueue_scripts', custom_color_picker_scripts);

Now create a new javascript file as like cp-active.js and keep it avobe defined “/js/cp-active.js” file path using bellows code.

jQuery('.color-picker').iris({
// or in the data-default-color attribute on the input
defaultColor: true,
// a callback to fire whenever the color changes to a valid color
change: function(event, ui){},
// a callback to fire when the input is emptied or an invalid color
clear: function() {},
// hide the color picker controls on load
hide: true,
// show a group of common colors beneath the square
palettes: true
});

Add a textbox to your settings page with a CSS class for the color picker, where you want to dispaly the input text. I have use “color_code” for input $variable.

<input id="color_code" class="color-picker" name="color_code" type="text" value="" />
