I managed to fix it. thank you. I played with all te stylesheets and when I pasted the following into the theme css of the word press it sorted it out.

#am-category .am-category-service .am-category-service-info{ background-color: white!important; }

#am-category .am-category-service { background-color: white!important; }

.am-category { background-color: white!important; }

.el-button {         color: white!important;         border-color: white!important; } 

.el-button span {       color: white!important; }

.am-category-service-color {       color: white!important;     }

.am-category-services-thumbs       img {       border: 3px solid white!important;       }

    span.am-category-service-title {         color: white!important;       }
