The ColorPickerTypeBundle extends Symfony2/3 form types, creates a new ColorPicker form type, to display a javascript color picker.

This Bundle use jscolor.

$ php composer.phar require xmon/color-picker-type-bundle

// app/AppKernel.php
public function registerBundles()
{
    return array(
        // ...
        new Xmon\ColorPickerTypeBundle\XmonColorPickerTypeBundle(),
        // ...
    );
}

If you wish to use Assetic Bundle to manage web assets, please follow this official guide. However keep in mind that symfony/assetic-bundle library has been deprecated and is not actively maintained and it's not compatible with Symfony 4+.

This bundle ships with JSColor library. You need to include a Resources/public/js/jscolor.min.js file in your templates in order to make ColorPicker field work correctly.

If you choose to use Assetic despite the fact it's deprecated, add XmonColorPickerTypeBundle to Assetic configuration.

# app/config/config.yml
# Assetic Configuration
assetic:
    bundles:        [ 'XmonColorPickerTypeBundle' ]

{% extends '@Acme/layout.html.twig' %}

{% block javascripts %}
    {{ parent() }}
    <script type="text/javascript" src="{{ asset('bundles/xmoncolorpickertype/js/jscolor.min.js') }}"></script>
{% endblock %}

Create new template extending default one:

{# src/Acme/AdminBundle/Resources/views/Sonata/standard_layout.html.twig #}
{% extends '@SonataAdmin/standard_layout.html.twig' %}

{% block javascripts %}
    {{ parent() }}
    <script type="text/javascript" src="{{ asset('bundles/xmoncolorpickertype/js/jscolor.min.js') }}"></script>
{% endblock %}

Set your custom template for Sonata Admin in config

#app/config/config.yml
sonata_admin:
    templates:
        layout: AcmeAdminBundle::Sonata/standard_layout.html.twig

You can use default form field template shipped with the Bundle or modify it in your own bundle and use it instead. NOTE: Please, use correct template depending your setup - with or without Assetic.

# your config.yml
twig:
    form:
        resources:
            # Add this one if you use assetic
            - 'XmonColorPickerTypeBundle:Form:fields.html.twig'
            # Add this one if you DON'T use assetic
            - 'XmonColorPickerTypeBundle:Form:fields_no_assetic.html.twig'

# your config.yml
twig:
    form_themes:
            # Add this one if you use assetic
            - 'XmonColorPickerTypeBundle:Form:fields.html.twig'
            # Add this one if you DON'T use assetic
            - 'XmonColorPickerTypeBundle:Form:fields_no_assetic.html.twig'

// src/AppBundle/Entity/MyEntity.php

use Symfony\Component\Validator\Constraints as Assert;
use Xmon\ColorPickerTypeBundle\Validator\Constraints as XmonAssertColor;

class MyEntity
{

    /**
     * @ORM\Column(type="string", length=6, nullable=true)
     * @XmonAssertColor\HexColor()
     */
    public $fieldName;

}

If you want change default message, try this:

    /**
     * @XmonAssertColor\HexColor(
     *      message = "Custom message for value (%color%)."
     * )
     */

$builder->add('fieldName', 'xmon_color_picker')

use Xmon\ColorPickerTypeBundle\Form\Type\ColorPickerType;
...
$builder->add('fieldName', ColorPickerType::class)
...

This form type can be used without any problem with SonataAdminBundle
