Hi Embruna,
Theme main built-in default color code is #89a452
(green) which treat as a color skin so that the user can easily change the color skin to their own corporate color via color skin option but this will not reflect to the list elements.
First remove the css code that you have paste and to set the same color for list elements go to Appearance > Customize > Ambition Theme Options > Custom CSS and paste the below CSS code then click on Save button.
#main ul a,
#main ol a,
#main ul a:hover,
#main ol a:hover {
color: #050466;
}
Change the above color code #050466
manually to the skin color you choosed.
It seems like you have set color skin to #050466
(dark blue) and want to set the different color for the links in the main content section rather then the color skin that you have choose then paste the below CSS code in Custom CSS option then click on Save button.
a,
#main ul a,
#main ol a,
#main ul a:hover,
#main ol a:hover {
color: #050466 !important;
}
Change the above HEX color code #050466
to your own HEX color code that you wish to have it on links.
Thank you!
