Changing the :checked style dynamically

Question

This code show the three buttons with check attribute.

I can change the color by clicking with :checked attribute in css.

However I want to change the color dynamically in javascript.

I can change the normal css by javascript but can I change :checked css???

          
$li = $(`<li><input type="checkbox" name="issueCheck" id="1" 
                    value="1"><label for="1">1</label></li>`);
// I want to set the :checked background-color for this 'red'.
$('#issueCheckUl').append($li);   
         
$li = $(`<li><input type="checkbox" name="issueCheck" id="2" 
                   value="2"><label for="2">2</label></li>`);
 // I want to set the :checked background-color for this 'red'.
$('#issueCheckUl').append($li);
            

    
$li = $(`<li><input type="checkbox" name="issueCheck" id="3" 
                   value="3"><label for="3">3</label></li>`);   
 // I want to set the color here 'blue'' 
 $('#issueCheckUl').append($li);
