Answer 1

Just give class or id to your anchors and then use css to give them different colour

<%= link_to 'Explore', explore_path, class: "black" %>
<%= link_to 'Submit Your Project', submit_path, class: "black" %>

And in css

.black {color: #000;}

This is very basic CSS and HTML You should checkout CSS and HTML
