If I understand your question correctly, you want to know how to use an angular directive to dynamically style the before/after pseudo-tags.

Instead of using ng-style, use ng-class to attach a class that will determine which before/after pseudo class to use.

And in CSS:

.breadcrumb li a:after { 
    content: " "; 
    display: block; 
    width: 0; 
    height: 0;
    border-top: 50px solid transparent;           
    border-bottom: 50px solid transparent;
    border-left: 30px solid hsla(34,85%,35%,1);
    position: absolute;
    top: 50%;
    margin-top: -50px; 
    left: 100%;
    z-index: 2; 
}

.breadcrumb li a.color-0:after {
    background: black;
}

.breadcrumb li a.color-1:after {
    background: blue;
}
