Theme Horse

Hi Rahul,

Add below CSS code in style.css file under attitude-child folder.

For navigation parent:

#access a {
    color: #777;
}

For drop-down:

#access ul li ul li a, 
#access ul li.current-menu-item ul li a, 
#access ul li ul li.current-menu-item a,
#access ul li.current_page_ancestor ul li a, 
#access ul li.current-menu-ancestor ul li a,
#access ul li.current_page_item ul li a {
    color: #777;
}

Change above hex color code #777 to your own HEX color code to change the color of the parent navigation as well as drop-down menu.

Thank you!
