Change font Color

Use your web browser’s developer tools to determine the name of the element and class (hover over the element in Chrome and click on inspect). Then, you can change the CSS for that element/class through the custom CSS editor. Select Appearance ? Customize section in your dashboard. Also, you can use some plugin in WordPress to add custom CSS to your site. You need to use the :hover pseudo-class in CSS in order to change the hover color of your element.

Hi, @giovannionias. Rose is right, you can add custom CSS to required classes.
Text in yellow boxes in the left upper corner of products has “onsale” class.
So if you want to change text on hover directly to that element, you can use something like this:

.onsale:hover {
    color: red;
}

Good Morning
I made changes to custom CSS as you explained, it worked!
Thank you very much, you were very efficient!

Thanks
