Hello,
In order to change the color of Category title and hide product number add this CSS to Theme Settings > custom CSS:
.hover-mask .category-title{
color:#ffffff;
}
.hover-mask .more-products{
display:none;
}
If you want to set different header for different languages, first of all you need to create them in Header builder as described here: https://xtemos.com/docs/woodmart/header-builder/create-new-headers-header-builder/
Then you can set one header in source page and another header in the target pate, enter the editing mode of the page and find this options in Page Setting (custom meta box from theme)
