Bootstrap 4：popover color

Question

如何修復bootstrap 4 popover上的箭頭顏色？

這是我的CSS：

.popover { 
    background-color: #212121; 
    color: $transparent_white; 
} 

這是我的HTML：

<div class="popover bs-tether-element show bs-tether-element-attached-top bs-tether-element-attached-center bs-tether-target-attached-bottom bs-tether-target-attached-center" style="top: 0px; left: 0px; position: absolute; transform: translateX(243px) translateY(294px) translateZ(0px);"> 
    <div data-reactroot="" class="popover-inner"> 
     <div class="component-rate-popover popover-content"> 
     </div> 
    </div> 
</div>
