Hello,

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

For without Sticky Menu color change, please try the following one:

body:not(.single-product) .whb-overcontent:not(.whb-sticked) .whb-row:not(.whb-with-bg) .menu .menu-item a {
    color: blue !important;
}

For the Sticky Menu color change, please try this one:

.whb-sticked .whb-row .menu .menu-item a {
    color: purple !important;
}

In this CSS, you can change the color to your choice of color hex code or color name. Hope this works out for you.

If somehow it doesn’t work out for you, then kindly please share your Site URL with us so that we can check this directly on your Site.

Best Regards
