Theme Horse

Hi Pip.partridge,
To change the hover color and also selected highlight color for the primary menu text
Go to Appearance -> Customize -> Ambition theme options -> Custom CSS paste the below CSS code and Click on Save & Publish button at the top of the options panel.

.main-navigation a:hover,
.main-navigation ul li.current-menu-item a,
.main-navigation ul li.current_page_ancestor a,
.main-navigation ul li.current-menu-ancestor a,
.main-navigation ul li.current_page_item a,
.main-navigation ul li:hover > a,
.main-navigation ul li ul li a:hover,
.main-navigation ul li ul li:hover > a,
.main-navigation ul li.current-menu-item ul li a:hover {
	color: #89a452;
}

Note: Please change above HEX color code #89a452 to your own HEX color code to change the color of the primary menu.

Also, If you upgrade the theme to pro version then you can set the color skin of each section with your own color also with lots of features.
Pro version will be available very soon.

Thank you for using our theme.

Hi Phil,

Sorry for that we forget that the character > will not support in the custom CSS for security reason.
So, Now you have to create the child theme and use above override CSS code.

To create the child theme create a new folder name ambition-child.
Also create a style.css inside ambition-child folder and paste the below CSS code:

/*
Theme Name: Ambition Child Theme
Author: Theme Horse WordPress User
Template: ambition
*/
@import url("../ambition/style.css"); 
.main-navigation a:hover,
.main-navigation ul li.current-menu-item a,
.main-navigation ul li.current_page_ancestor a,
.main-navigation ul li.current-menu-ancestor a,
.main-navigation ul li.current_page_item a,
.main-navigation ul li:hover > a,
.main-navigation ul li ul li a:hover,
.main-navigation ul li ul li:hover > a,
.main-navigation ul li.current-menu-item ul li a:hover {
   color: #00ffff;
}

Now activate your child theme ambition-child via dashboard and also do not delete the main theme ambition because it will be a parent theme of your child theme ambition-child.

Hope it will help.

Thank you!
