Hi,

So, please try using the below Custom CSS code and paste it to Dashboard >> Theme Settings >> Custom CSS >> Global CSS section:

.wd-nav-product-cat>li>a {
    color:blue !important;
	text-shadow: 2px 2px #ff0000 !important;
}

For hover.

.wd-nav[class*="wd-style-"] {
	--nav-color-hover: yellow !important;
}

Change the color as per your need.

Best Regards.
