Would you like to make your reCAPTCHA match your website’s dark theme? While Google’s Checkbox v2 reCAPTCHA comes with a light theme by default, you can easily switch to a dark theme using a simple JavaScript snippet. This enhancement is perfect for sites with dark color schemes or when you want a more sophisticated look.

This guide will show you how to change your reCAPTCHA theme from light to dark.

## Understanding reCAPTCHA Themes

By default, reCAPTCHA displays with a light theme. However, Google provides a built-in dark theme option that you can enable through a simple attribute change.

This theme change applies to:

- Google Checkbox v2 reCAPTCHA
- Invisible reCAPTCHA v2
- hCAPTCHA

## Prerequisites

Before changing the theme, make sure you have:

1. Created a form in WPForms. If you need help, check out our guide on [how to create a form](https://wpforms.com/docs/creating-first-form/).
2. Set up reCAPTCHA on your form. For setup instructions, review our documentation on [setting up reCAPTCHA in WPForms](https://wpforms.com/docs/how-to-set-up-and-use-recaptcha-in-wpforms/).
3. Enabled Google Checkbox v2 reCAPTCHA in your form’s **Settings** » **Spam Protection and Security** tab.

To switch to the dark theme, add this code snippet to your site. If you need help adding custom code, please review our tutorial on [adding code snippets](https://wpforms.com/developers/how-to-add-custom-php-or-javascript-for-wpforms/).

This code works by adding a `data-theme="dark"` attribute to the reCAPTCHA element. For additional customization options, you can refer to the [reCAPTCHA Developers Guide from Google](https://developers.google.com/recaptcha/old/docs/customization).

Once the code has been added to your site, your captcha theme will now be set to **Dark**.
