Hello Esteban,

I am really sorry for the delay of this reply as it is a weekend for us here. Try adding the block of css codes below into your template's css file,

div#es-wrap .search-input-wrap .btn-search,

div#es-wrap .btn-clean,

div#es-wrap .btn.btn-es,

div#es-wrap .es-story .es-story-privacy .es-privacy-toggle i,

div#es-wrap .es-privacy .es-privacy-toggle i{

    color: #666 !important;

}



#editor-xtd-buttons .btn-toolbar a,

#editor-xtd-buttons .btn-toolbar i{

    color: #666 !important;

}
