Can the recaptcha icon be customized with a new hue?

I have been attempting to alter the captcha icon/logo in recaptcha v2. Initially, I tried to modify it using regular CSS without success. Then, I experimented with jQuery to determine if the iframe had loaded completely before proceeding with the change.

The icon/logo is fetched from a Google website via a CSS file where they reference the element .rc-anchor-logo-img. This particular div contains the icon/logo and is styled as follows:

.rc-anchor-logo-img {
    background: url(https://www.gstatic.com/recaptcha/api2/logo_48.png);
    background-repeat: no-repeat;
}

This represents the original logo provided by Google.

And I am looking to replace it with this one.

If anyone could assist me with this task, that would be greatly appreciated. However, I suspect that the logo may not be customizable. Nevertheless, thank you for taking the time to read this or provide feedback. Have a wonderful day.

Answer №1

Modifying the CSS of HTML within an iframe is not permitted, as it goes against Google's policies. However, there is a workaround by overlaying an image on top of the iframe.

You can try placing the captcha code inside a div and then inserting a transparent PNG icon within the same div. Position the image absolutely relative to its parent div, and adjust the CSS properties (left, top) to overlap it onto the icon.
