Yes, there is: https://make.wordpress/core/2012/11/30/new-color-picker-in-wp-3-5/

1. You should enqueue scripts and styles...

add_action( 'admin_enqueue_scripts', 'mw_enqueue_color_picker' );
function mw_enqueue_color_picker( $hook_suffix ) {
    // first check that $hook_suffix is appropriate for your admin page
    wp_enqueue_style( 'wp-color-picker' );
    wp_enqueue_script( 'my-script-handle', plugins_url('my-script.js', __FILE__ ), array( 'wp-color-picker' ), false, true );
}

2. ... add an input...

<input type="text" value="#bada55" class="my-color-field" data-default-color="#effeff" />

3. ... and call wpColorPicker function

jQuery(document).ready(function($){
    $('.my-color-field').wpColorPicker();
});

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="" />
