I want to change the tooltip arrow color to red. I've googled about for an hour and the snippets that I found did not work.

My last attempt was:

.tooltip-arrow {
  border-right-color: red;
  border-left-color: red;
  border-bottom-color: red;
  border-top-color: red;
}

The tooltip is positioned right, poiting left.

In bootstrap 4.1 you can use: 

.bs-tooltip-auto[x-placement^=bottom] .arrow::before, .bs-tooltip-bottom .arrow::before {
    border-bottom-color: red !important;
}
.bs-tooltip-auto[x-placement^=top] .arrow::before, .bs-tooltip-top .arrow::before {
    border-top-color: red !important;
}
.bs-tooltip-auto[x-placement^=left] .arrow::before, .bs-tooltip-left .arrow::before {
    border-left-color: red !important;
}
.bs-tooltip-auto[x-placement^=right] .arrow::before, .bs-tooltip-right .arrow::before {
    border-right-color: red !important;
}

I am using bootstrap 4.0.0-beta.2. and this code worked for me.

.tooltip.bs-tooltip-bottom .tooltip-inner {
    background:#444 !important;
}

.tooltip .arrow:before {
 border-bottom-color:#444 !important;
 border-top-color:#444 !important;
 }

Bootstrap 4.0.0 & Popper.js

Left arrow tooltip:

.tooltip .tooltip-inner {
  background-color: green;
}

.tooltip .arrow::before {
  border-left-color: green;
}

Just add in to your CSS.

I usually override bootstrap 4.3 tooltip styles like this, which should be straight-forward:

/*Tooltip*/
.tooltip {
  font-family: "Roboto", "Tahoma", "Helvetica", sans-serif;
}

.tooltip > .arrow::before {
  border-bottom-color: #757E94;
}

.tooltip-inner {
  background-color: #757E94;
  color: white;
  font-style: italic;
}
