How to change the green color of the left?

Usei Quantity gift registry, apenas como mudar a cor verde dos left ?

I'm sorry, but are you referring to the quantity color? In my sample screenshot, I boxed in the green quantity color. If you are referring to that, you will need to inject the CSS code below into the widget's CSS block https://www.jotform.com/help/428-How-to-Inject-CSS-Codes-to-Widgets.

span.items-left {

    color: red;

}

You can replace the "red" value to whatever color you want or even the hex color you can use that.
